This post's back to cast puzzles again, I haven't been posting about these in a while (to be honest, I haven't been posting ANYTHING in a while, but the last Cast Series were a few posts back.) The puzzle today was sent to me courtesy of Puzzlemaster. It's called the Cast Medal, and true to it's name there are two medals linked together. The whole puzzle was bronze-colored giving it an aged feel-Hanayama's got several puzzles with this kind of finish (NEWS, O'Gear, Enigma, Baroq, Helix, Radix...) and the finish always looked great! A glance on the Puzzlemaster webpage shows a five-star rating. Hmm, this might be a interesting one!

Cast Medal

The Hanayama description reads: "Two ancient looking medals engraved with a flowing river and a swimming salmon. Will you be able to retrieve the ring the salmon holds in its mouth? This puzzle was designed by British puzzle creator, James Dalgety, after the legend of the Ring and the Salmon, which figures on the coat of arms of Glasgow City. The theme of this puzzle is "Legend." So there is, a ring in a hole on the 'salmon' plate... Looks like that's our mission then!

Looking at the puzzle, one plate had the salmon swimming beside a island in the water, the other contains several small rocks. It would seem those are going to make the ring's journey to freedom difficult! Each plate had some holes too, the 'island' plate had six while the 'salmon' plate had two. Quick inspection shows where the exit points are (curiously there are two, one on each ring) though the problem is getting there.  You'd be tempted to turn the ring right down the plate and out of the exit, but you can't because the island mentioned above is there, and another whole plate is in your way on the other side. Oh well.

Cast Medal solved

At first there seems to be nowhere for the ring to go, but there is. Some twiddling saw me finding a step which turn the puzzle into a unique position, then things flow on. Several minutes later the ring lay freed! There was one part in the middle that delayed me a bit-it's unconventional and slightly unexpected, but nevertheless I got past. Alright, simple and fun...

That's when I noticed I used 1 out of 6 rings on one of the plates! 

Things are a bit fishy... (no pun intended) They aren't just there for decorations, are they? Another go, then. This time I managed to do something I didn't thought of before-smiles begin to spread as the ring winded through the six holes-and pop! Out it goes. As it turned out, the gap on the ring was big enough to allow for some more

non-intuitive moves, which makes way for the ring to use only one hole. Brian here too stumbled upon this alternative solution. The move was probably unintended, though fun to go through this alternative. The correct latter steps were reminiscent of another level 2 Hanayama, the Cast Plate. 

In puzzling value, the puzzle was on the easier side of level 2. Most of the solving process was fairly straight-forward. Experienced puzzlers should solve the puzzle with no problems. However this doesn't mean this isn't a good puzzle. Interesting combination of different kinds of moves were combined together. It was the perfect introductory puzzles for the newcomers or non-puzzlers. Also for those who got it the right way first try-I ask you to free the ring again, with one hole used! Puzzlemaster has the Cast Plate, as well as the rest of the Cast series for sale here.

Scott's Wonders 1: Stewart Coffin's Involution Puzzle

Puzzle: Involution
Designer: Stewart Coffin
Craftsmen: Scott Peterson

ST: ~15 min by Kevin Standard

How time pass by! I am ashamed to have not kept my promise! Weeks wheeze by without me even realizing it. I really appreciate people like Gabriel, Kevin and Allard who manages to pick up a steady posting pace-their posts aren't quick, sloppy one either. Please do forgive me, and to make up I'll present you today with a design from Stewart Coffin: The Involution.

Around the end of last year I discovered the Rosebud surfing in the puzzle blog-dom (they do a great job of bankrupting puzzlers, you know who you are! And no, this amateur is not good enough to be one of them!). I found out more about the puzzle with the help of two good puzzle friends Oli and Kevin, then eventually got in contact with Scott Peterson, who was long known in the puzzling world as a professional craftsmen since 2003. (Neil have visited Scott and made a blog post about it here) As it happens Scott has made a small batch of Rosebuds in the past, and those who received them were more than happy. I was warned it didn't come cheap, though. For a craftsmen like Scott it's more than reasonable-but having nearly bankrupted myself by the latest Wil order it's not good! 

The Involution puzzle
(The pictures really do bad
advertising for Scott-especially mine!
You need to see it for yourself!)

Scott responded quickly with a big yes, then several days later delicious pictures of the puzzle followed. I was so impressed that I asked him if he's got any other goodies to spare? More pictures came and eventually I settled on a beautiful Involution which really stands out from the rest in the stream of pictures. That particular copy for those interested was made from Bubinga and Ziricote for the corners, two types of wood fitting together just fine! Some time passed before payment were sent largely because of a delay on my part (sorry Scott!), after which the puzzles were quickly sent and received. 

First thing I noticed was the size of the package. The Involution, the larger of the two, was about 7 cm across, but the package it came in was more than three times as high! Most of that space were inhabited by foam bits showing Scott really cared for giving the puzzles a safe voyage across. Digging through the cushioners I got out two plastic wrappings showing various kinds of woods in their finest. Since the puzzles were some of my first wooden ones at the time I don't really know what to expect but Scott's given the puzzle care down to the last detail including very nice lacquers and rounded edges.

Involution pieces

So taking the puzzles out, I toyed with the Rosebud for a bit (more of that later if odds go in favor) before launching myself to the Involution. Something worth mentioning was that Stewart Coffin had designed the -volution (yes, and -volute... you picky fellows) puzzles in such a way so the pieces form a kind of windmill pattern on every side when assembled. Clever! To design a puzzle like that with this pattern to keep in mind was nothing small-I still fail at even getting anything to interlock!

A close-up of the infamous key piece that
have caught many a puzzlers unwary...

Down to the solving, it's a interlocking cube with a seemingly low level of 1.2.1.1.1, though always remember not to judge a puzzle by it's level! Puzzling-wise it wasn't hard, but certainly interesting. For example: how do one usually start solving a interlocking cube? The normal way was to take out the key piece, which gives a problem right away. As Allard has observed, the pieces Scott crafted had such accuracy to the point that there is virtually no gap, movement or anything that can help you find where the first piece is. I spent a solid five minutes just to find it! The thing almost zinged across the room when I got it out! 

A shot of the puzzle half solved
(and a wink for those who solved it)

Next comes a move that reminds me of these sneaky coordinate motion puzzles where it's the right grip or nothing... Down the road the puzzle throws at you pieces not quite where you'd think they'll come out, movement sending you off to the wrong direction, and a rotation to keep it all good fun. A combination of Coffin genius and Scott's skills also made it possible to pick up the puzzle at any stage of solving and it won't be easy to figure out the next piece.

Definitely a superb puzzle gain. It's a great design, and having it made by Scott pushed it up to the highest display shelfs. The Involution along with many other Famous geometric designs from various designers is also available from Scott in superb quality with a pm to him in the renegades forum. Or if you're not a member, just ask one of the many kind puzzlers out there like I did-I'm sure they be willing to help you out.

I give up in shame...
Hopefully only for now.

End note: If you're wondering why I didn't review the Rosebud first which started it all, the poor thing was taken apart for images and stayed that way since.

Medallion

This is the Medallion puzzle, invented by the puzzle genius Oscar van Deventer and brought to me by Puzzlemaster. Thanks Puzzlemaster for sending me this puzzle free for review.

The Back

The Medallion was made out of anodized stainless steel, excellent quality as Hanayama puzzles always were. It was conveniently palm-sized, having a good weight when held. Being a medal themed puzzle, it was shaped around one from top to bottom - I think it just looks brilliant with the Gold & Silver anodized plates and it's medal shape! The slot on the top was possibly meant for inserting a strip of ribbon to wear, though I for one thing wouldn't be wearing it anytime soon.

Medallion Opened

This is a sequential movement puzzle (5.5 in the Jerry Slocum classification if you are precise), and it's goal was to navigate the pins through the two plates until they reach the holes at which point the puzzle would come apart. The puzzle was navigated by rotating the two disks and pushing/pulling of the two halfs of the medal. This is one of the more unique maze puzzles to solve as there aren't two mazes, but four! In order to move a pin in it's maze one of the adjacent mazes would also have to be move into the correct position, which requires another maze to be positioned. In the solving progress one would have to look after each maze, flipping back and forth to get things right. To puzzle veterans it'll be a breeze, but even the non-puzzlers would be able to solve this with a bit of persistence.

Medallion Disassembled fully

My first opening probably took me around 5 minutes (though mostly with blind luck), then I had a few more tries before I got fluent with the opening. The puzzle was not overly hard-when one first plays with the puzzle it seems complicated, but you will find that as the solving goes, the movements flow along. Up until today, I still never bothered to memorize the exact steps, so each new solving was a bit of challenge, even if just a bit, and I throughly enjoyed opening it every time.

All in all another great Oscar design with excellent Hanayama quality - for my two cents, when those meet together, you just can't pass it pass up. It is for sale at Puzzlemaster here for about $20 U.S dollars.

Free the Key

Puzzle: Free the Key
Brand: Puzzlemaster
Inventor: Oscar van Deventer

ST: ~15 min

Been quiet around here recently - I do apologize for this, and I hope to improve my posting rate from now on. Well, here is a post to change the situation.

Free the Key

Free the key was a puzzle that came with several others from Puzzlemaster back when I first started puzzling, but haven't decided to write about it until now. It came simply in a blue plastic package that tells you the name, it's difficulty rating, and (helpfully) states that the objective is to remove the disk from the aluminum key. Taking it out you can see some marks on the parts that gives hints about the building quality - but isn't too troubling considering the cheap price. The thing felt quite sturdy, and would've done some damage if it had an encounter with one's foot!

This puzzle is another well known Oscar design, and as with quite a large portion of his designs this is a maze puzzle. It was in my opinion quite something unique, taking keys to be the theme. As you can see there's several notches on the disks which interacts with the key to create a fairly complicated maze, containing several dead-ends along the way to trip you up.

Job done!

So taking the puzzle you start manipulating the disk and in minutes was close to the end-only to be stopped in your tracks two-thirds from the end. Trying again only results being stuck in the same place. Time to explore a bit! After a while you'd find some more avenues to get into, enabling more fiddling - Suffice to say the solution wasn't trivial, requires you a bit logical thinking and planning before getting the job done. A neat little puzzle that would keep you thinking for a while.

Again a great design by Oscar-and I think I have an idea of why both reviews on it's puzzlemaster page gave it a five-star rating. You can get a copy of the puzzle from either Puzzlemaster, or Sloyd for a reasonable price.

Alcatraz the Puzzle

Alcatraz Puzzle

Every puzzler now and then would probably get to the Alcatraz Puzzle after a bit of surfing on the web. It is a fairly intriguing puzzle with a ball trapped inside a square cage with bars on both the front and the back blocking any possible means for the ball the escape. It lively represents the real-life Alcatraz Prison, as from what I've heard that's about how big the cells are in there to their prisoners. Quite something curious enough to be picked up on first sight.

The inventor was a magician, and was greatly interested by puzzles too. When he discovered that there's no puzzle in the world that satisfied him, he decided to design a good puzzle that he'd never met. And so the Alcatraz was born. It was originally used for his magic shows, but then developed to be the well-known puzzle. You can read the full story here.

I've got the puzzle from quite an earlier order from Puzzlemaster along with a few others, but haven't decided to review it until now-I do have a reason which I'll explain more later. So fiddling with the puzzle the ball would move a couple of millimeters and except from that the brass bars rotate freely and move up and down a bit, there's seemingly no possible movement whatsoever. I think that it is actually pretty obvious how the ball comes out-the challenge lies in working out how. I must've spent rather a good hour on this one without having the slightest progress-the puzzle gives absolutely no feedback!

Jailbreak!

Finally I gave it up and looked at the solution. Have to say it surprised me! I would say that the solution of Alcatraz is very hard to find, but that's not because it was designed well. It's because no good-seasoned puzzler would ever do that to their puzzle! I'd say that Alcatraz is a good idea with a great appearance but poorly designed. No one would consider a puzzle box as a good puzzle if it has been glued together and the solution was to hit it with a hammer... Get the idea? (do not get the wrong idea-you do not break Alcatraz to solve it but it does require some serious force.)

Not quite a good experience this time and although as stated on the website most people give it a very high rating I'd be hesitant to recommend it to others. And although with time it does became easier to open without that much force I still have pain (yes pain!) opening it. It's hard to write a negative review but I feel the need to state my thoughts about that puzzle as people would be taking review into account before buying puzzles. I am sorry if I offended anyone.

Rush Hour App

The Original RushHour

Puzzle: Thinkfun Rush Hour App
Brand: Thinkfun
Inventor: NOB Yoshigahara
ST: N/A

The famous RushHour is a world-known puzzle invented by the great inventor NOB Yoshigahara and brought to life by Thinkfun, a company selling many different kinds of creative brainteasers and puzzles. This was one of the puzzles that even a non-puzzler would know-Try asking someone who does not play with puzzles and ask them if they know about either the Stickman Milestone Box or RushHour-Which one stood a better chance?

For those who don't know, the RushHour is a sliding tile puzzle with cars of certain lengths in a grid blocking each other, representing a traffic jam, and the goal was to free the red car from the exit. Unlike other sliding tile puzzles the cars are only limited to move in two directions, which added up the difficulty. Lots of thinking and planning were required to pass the harder levels.

YYYay!

Lvl 19 on the app version 

Anyway, the puzzle is so well-designed that it even brings itself on the apple market! Thinkfun's got three of their puzzles turned into apps-RushHour, Solitaire Chess, and Chocolate Fix, all of which I favor. And the nice folks at Thinkfun were kind enough to give me free codes of all these for review... Thanks Thinkfun! Whilst the puzzles has 48 challenges, softwares has a humongous amount of level with 100 at each difficulty! This certainly would keep puzzlers busy for a bit of time... Quite a bit... Softwares also had their advantages shown in the app with all the scoring, hints, and immediate reset button, in my opinion all nice features.

Now the concept of RushHour allows not only hundreds, but thousands of different combinations to come, so many new developments came-Another app called RushHour! Holiday edition was released, and I've heard that there's new level packs being sold for plastic editions... Methinks new levels would never cease to come for this traffic jam puzzle... Very nice one Mr. NOB! It's one of the footprints he left on earth before the great master went away.

The RushHour! Plastic can be purchased from here, and the app version can be purchased rom the app store for about 2.99. Some likes the solid and sturdy feel of the plastic version, others prefer the functions and portability of the apps... Each to their own.

Temple Escape!

Temple trap-level 17

This is Temple Trap from Smart Games (Thanks for the correction), a company which sells puzzles with pieces to move with and challenge cards for you to orientate them in order to start the challenge. They're mostly made in plastic which enables the cheap price-and with 48 different level challenges in one puzzle you really can't go wrong in buying one.

Lvl 17 solved

Upon selecting a level you begin by arranging the tiles and placing the figure. Then, try and move the tiles so that the adventurer can escape from the temple from the exit on the top left. This is not an puzzle like the normal moving tiles because you have to be moving the figure corresponding with the tiles making a way for it. Then there were the added restrictions like the tile the figure was on cannot be moved, the figure can only get on green tiles by stairs etc... All to make this puzzle a fairly good challenge. In order to pass each level planning ahead is required as you sort out the steps one by one, and sometimes you'll get lost in the steps and go around in circles-so keeping track of what you've done is also recommended.

Having 48 levels with different difficulty I think it is suitable for all people from non-puzzlers to the masters, and would definitely increase your puzzling skills going up the levels one by one. It also includes a plastic cover so you can take the puzzle wherever you go and not worry about the pieces falling out. In my opinion it was a well-designed puzzle with a nice theme.

You can purchase it here from Smart Games, but I think they only ship to the US for now so I guess others will have to just keep waiting!

Houdini's Torture Cell puzzle

Puzzle: Houdini's Torture Cell

ST: ~30 m

Opening Bat

Back in December 2010, 50 copies of a limited edition puzzle called the Opening Bat was released. It is a mammoth sequential discovery puzzle that, according to Brian's own words, "As far as sequential discovery puzzles go this one's on steroids!" Taking ten years to design. The Opening Bat is a gigantic puzzle with "multiple puzzles in one", and has just everything to win it countless awards. I regret to this day having not brought it while I still have the money. It is one of the best puzzles ever made/designed. Being such a puzzle king it's not going to come out cheap, and with only 50 copies many puzzler missed out on the fun. Brian received amazing feedbacks for this puzzle- 

"...this is an awesome puzzle!...As far as sequential discovery puzzles go, this one will be hard to top!" - Brian Pletcher

"the One to Rule Them All...definitely a very cool puzzle...much more elaborate than any sequential discovery puzzle I’ve seen" - Jeff

"Brian has done a great job and there's clearly a lot of time and care went into the puzzle. Hat's off to you sir, it's a great puzzle!" - Neil Hutchison

"an Opening Bat is never going to disappear in among a collection of puzzles – it is going to stand out...Brian Young, you ought to be proud of this, very proud!" - Allard Walker

Well, Brian felt that it's too good an idea for just an limited edition and remakes the last part. And here the Houdini's Torture Cell is born!

Houdini's Torture Cell

With the sob-story of missing out the Bat still in my mind, I was keen to not miss the Torture Cell when it came out-and the result of that is having it sitting on my desk right now. The puzzle was sold out literally days after I've brought it-Phew!

Houdini's Torture Cell is a sequential discovery puzzle just like it's older brother, where you'll have to follow a number of steps in order, and all you need to solve the puzzle (tools) is contained within the puzzle itself. It was themed around Houdini's Water Chamber-whereas the wooden peg represents poor Houdini hanging upside-down in the water chamber (a.k.a Torture Cell), and your job is to rescue the great escape artist from it's fate.

Now, as I said previously, the puzzle was a remade of a part of the Opening Bat-but Brian has made modifications to it that made it a much easier puzzle by using acrylic. Being able to see what's going on lowered the difficulty of the puzzle-but hasn't lowered it's rating. Actually, many puzzlers reviewed the puzzle as one of their favorites!

So why is that? I say that it's a fun puzzle to fiddle with, you're aware of progress and little A-HA moments-And finally you make that last step and Houdini is out! All that and the clever mechanism made it a very good puzzle.

A not-so-good looking

Houdini out of his chamber

So upon receiving the puzzle you see Houdini and a ball bearing in the Cell, and a stand beneath it. I've been giving this to lots of people and the first thing they wanted to do is always wanting to get that ball up that stand-Hilarious-(Believe me, you're NEVER going to get it sitting there by dexterity alone!)-Than finally getting Houdini out with a satisfying motion. I wasn't known to be much of a experienced puzzler-and although made the right discovery did not use it the right way! It took me a LONG time to figure out what was to be done. Sadly the step can be easily flunked with random shakings-It is not the solution! The real motion is much more elegant. Finally after spending half an hour at this puzzle I got him out-Sense of achievement!

A fun puzzle to fiddle with, MOST people finds the solution pretty quickly and the solve was rewarding. At the time it was already sold out but if you ever come across one of those it's definitely worth a go.

Hanayama Cast Puzzle: Cast Cage

ST: ~15 m

Cast Cage

This is the Cast Cage from Hanayama, rated level 3 on their scale of 6. Having black and gold as the color choice, it has a unique appearance. This puzzle was similar in concept to those "free the..." puzzles, such as this one, but also had it's own different features. A dark cage, with openings on four sides, imprisons a star, and your goal was, of course, to rescue it. The star's legs has different lengths, and the openings were also different shapes. Only one was (supposed to be) the correct exit, and you'll need to find both the correct opening as well as the series of movements of the star in order to take it out.

Star out of it's prison

After a few tries I quickly deduced where the opening should be and after some fiddling the star was out! Putting it back I tried to do the solution again to make sure I remember it, and showed it to a friend who was at the time with me. He was also able to have done it pretty quickly- but had it out on a different side! Thinking he's broken the puzzle a panicked Will took the puzzle back only to find that there's not just one solution... There was three! I don't know if it was a defective on my puzzle or a general problem, but with the design that's a little inconsistency. Somewhat similar to my experience with the Cast H&H-It is not too big a problem but does let down the overall rating of the puzzle.

Despite that the Cage was another good cage-type puzzle to fiddle with, and I say with Hanayamas the more the better! And as usual, the link to the shop.

Cast H&H

Here's another Cast Puzzle for review: the H&H. At first sight it doesn't immediately show how it should work-but after picking it up it became fairly obvious, like the Cast Disk. The puzzle consists of two "H" shaped pieces intertwined with each other, some grooves on the puzzle makes it not possible to just pull the pieces apart but having to go through a serie of movements in order to separate them. The puzzle is a 3-D maze, and has some really interesting moves. It somehow resembles another puzzle in the series, the Cast Keyring, with similar aspects. As you can see in the photo the name and brand is engraved onto one of the piece, a little detail Hanayama puzzles always have.

The H's in pieces

Now although the puzzle was rated 5/6 in my opinion it was rather easy and I personally would rate it as more of a 3 or 4. Though there are other problems such as solving the parity issue the maze don't have too many dead-ends, and when it do, they don't extend long. I solved the puzzle rather quick-in total there were 26 moves at my count, although there was one kind of move the solution did not use, which is a bit let-down for me. A few days later, I was surfing on the web, and finds a copy of the solution of the H&H. But the problem is-the official solution was totally different with mine! It turned out that the puzzle has actually multiple solutions, and th official solution includes all six moves, not counting that it was the shortest one with only 20 moves (no pun intended). I'm not a big fan of puzzles with more than one solutions, but I guess for some maze puzzles it's just impossible to prevent that. Despite that, the Cast H&H pops out on the range of maze-type puzzles because the way the pieces interact with each other is very clever, maintaining your interest and made the solving progress fun.

On the shelf the nice silver coating made it look nice, and with the reasonable price you just can't go wrong with buying one here.

Revomaze IV Extreme

Puzzle: Revomaze Invisible Extreme
Brand: Revomaze
Inventor: Chris Pitt
ST: ~2 Weeks

Revomaze Invisible Extreme

So after my rather expensive CE purchase I was completely hooked onto Revomazes, and when another limited edition popps out on the website, I was not one to miss out.

There was quite a talk in the forums about a invisible Revomaze coming out and I finally waited to this day - you can read about the post here. Chris has used a new machining technology that melts air then shapes them. The Revomaze IV has only been produced 25 copies - quite a small amount for a limited edition revo. But considering the costly technique I think it's reasonable. Been saving for a month to finally purchase it - you won't want to know the cost.

The serial number - IV0017

Being brought the puzzle on April 1st, it actually arrived quite quick. But since Chris designed the box as also invisible it took me 2 weeks to finally realize it! Besides the puzzle, opening the box was a free puzzle itself, since when someone opened air before right? It took me awhile to figure out the solution. Now I have to say although the Revomaze IV was expensive it was definitely worth the price. The machining was of very high quality, and I was satisfied indeed! After washing off the WD40, I began working. What a puzzle!


Now I have to say the Revomaze IV is unlike any other puzzles. For one thing the feel is totally different. It was smooth to the point that you won't even know if you dropped into a trap line until you were back to the start! This had added to another level of difficulty. Second it's the weight. Previous Revomazes are all heavy, thus causing additional soreness. There is none of that problem on this maze. But the only downside to the Invisible is that when one's toying with it out in the public, he looks like a complete fool, as they can't see what's going on.

I have been going well on the first section when a moving part Chris puts in there totally stumps me. I have been going back and forth but to no avail. It isn't until when I completed my map on that part did I see what can be done to progress through - that was a big "A-HA" moment! Then comes the second part which is very tricky to pass through - Chris has used the speciality of air to make a very hard puzzle. That part took me at least a week to do - as I am not used to an AIR puzzle! ARGHGHGHRRGGH!

Solved! 

Finally I was down to the last section. Only thing I can say is,Chris has gone to the point of using MAX dexerity, and when you finally gotten through "the tightrope", their fingers are already falling off... So finally after about 2 weeks the Revomaze Invisible Extreme was open! It was a very hard maze and my opening time was nowhere in compare as my last one. But having seen the insides I have to say it was VERY cleverly designed! I would definitely look for more of Chris' designs.

You can buy the Revomaze Invisible Extreme here, although keep in your mind that the purchase page was invisible too. Be quick, as it was very popular and the 25 might be sold out soon. EDIT: The Revomaze Invisible Extreme was officially sold out. Congratulations to the current owners!

Have fun!

Nine Linked Rings

This is the Chinese Nine Linked Rings puzzle. Although being famous not much puzzlers seem to have it. It has been manufactured by quite a lot companies, and goes on to have many styles. This puzzle also have quite a history to it. It was invented by Zhuge Liang, a chinese teacher who also invented other things and led many successful battles. According to history he had invented this puzzle for his wife to play with when he's at war.

Half-Solved

The puzzle has basically two parts, the "sword" and the rings. Nine rings entangle with the sword and with each other, and your task is to take out the "sword". The puzzle is based on a simple principle, and for a ring to be taken on or off you have to meet certain requirements, so that's why you are taking them  repeatedly on and off to try and get the puzzle solved. For example, when you want to get the ninth ring off, the eighth has to be on, and in order to do that, the seven has to be on... In total there's 341 steps to take all rings off, and boy, won't that hurt!

Separated... 341 steps!!!

This puzzle is not particularly fun to solve, as it's just doing the same thing over and over again, but still,  logic thinking is required. I would not recommend it to serious puzzlers, but juniors would receive lots of fun. The Nine Linked Rings can be gotten from MrPuzzle.

Hanayama Cast Puzzle: Cast Elk

Puzzle: Cast Elk
Brand: Hanayama (forgive me)
Inventor: NOB Yoshigahara

The intertwined elks

This is the Cast Elk from again Hanayama, with the highest rating of 6. I currently was stepping up from the medium range and buying lots of harder puzzles. The elk is one of them.

The designer's name engraved
on one of the pieces

This puzzle is, indeed, shaped as two elks, their horn entangled, and the letters NOB, the name of the designer, engraved onto one of the pieces. Then of course, your task is to separate them. I have classified the Hanayamas into two categories: the first includes puzzles that needs just a few steps to solve, but requires hard thinking. Examples may include Cast Nutcase, Cast News, Cast Spiral, and this one. the other is maze-like puzzles that require a long series of move to solve, and most of them requires the trial and error method (although Cast O'gear is a exception, see an earlier post). Puzzles that fit into this category might be Cast H&H, Cast Disk, Cast Keyring, and Cast Bike. I personally prefer the first one, as they require more thinking and not luck.


Back to the topic, Cast Elk is one of my favorite puzzles because of this reason. They are also beautifully crafted with detail, a common trait among the Hanayamas-beautiful and hard. I have been manipulating the two pieces for some time and was just going in circles. The horns' shape interact with each other to just block you from the last move!

The Elks separated

Later in the day I was watching TV, and taking the puzzle out from my pocket I suddenly found that it was in a whole new position I have not gone to-Kevin have I found another Magic jacket ? :D From that point I was able to progress and finally separate the two pieces. It turns out that I have tried a similar thing before, but the designer has made the two pieces slightly different, so out of the four similar moves only one works. I counted and there were about three moves total in order to save the Elks, but they were really tricky!

Overall the Cast Elk is a lovely puzzle to get, it's a "beginner" level 6, and as always worth your sacrifice. The Elk can be brought from here.
