ThinkFun 36 Cube Review

ThinkFun 36 Cube
Average Reviews:

(More customer reviews)
My 11 year old son got a 36 cube for his birthday and played with it for many hours. From that standpoint, it's a reasonable toy. I found it interesting to think about just how difficult a puzzle this is. There are 6 different colors and each color has 6 pieces of 6 different heights. At first thought, there could be a huge number of possibilities but there are also posts that the pieces have to sit on and they constrain the possible locations of the colored pieces. The next paragraph of this review contains something that many would consider a spoiler but I feel it needs to be said. If you plan to buy this puzzle for someone else and have no intention of trying to solve it yourself, you should read on. If you think a good puzzle is one that is easy to understand but a challenge to solve, like a rubic's cube, you might want to read on because you might not like this puzzle.
ThinkFun describes this puzzle as having an Aha moment when solving it. There are many types of Aha moments, like the moment you realize a new way to deduce a value in Sudoku, or, when you realize you have been betrayed by someone you trusted. I enjoy the first type but not the second. Unfortunately, I consider the Aha moment in this puzzle to be in the second category. With this hint, some may want to stop reading here and take the challenge this puzzle offers.
After wondering how many combinations there really are in this puzzle, I decided to write a computer program to explore its possibilities. My program determined that there were no solutions. I checked my logic carefully and there were no mistakes. This prompted me to do a quick web search and I found that the Aha moment in the solution is when you realize that this puzzle is not what it first appears to be. One would naturally assume that all the pieces of the same length are identical but they are not! To hide this fact, unlike most puzzles, this puzzle does not come from the factory in the solved state. Had it come solved, people would realize that some of the pieces were in places where they shouldn't fit. This left me feeling that Think Fun cheated. It's the most challenging puzzle in the world because, if you don't realize there's a trick to it, it's impossible! I now view it as a practical joke and not a puzzle. Once you realize its secret, it's not an extremely difficult puzzle. After adjusting for the secret, my computer program solved it after placing under 2000 pieces. Unlike Rubic's cubes and Sudoku puzzles, I doubt if there is an elegant way to solve this one so it's not a very enjoyable puzzle.

ThinkFun Zig Zag Knot Review

ThinkFun Zig Zag Knot
Average Reviews:

(More customer reviews)
My column "Modern Burr Puzzles" was partially responsible for the Gordian's Knot puzzle. I also pushed the idea rather heavily to Thinkfun. Even though it was a ridiculously difficult puzzle, it was very fiddly and fun -- a lot happened while playing around, and it still stayed together.
With hindsight, it was a ridiculous idea. The puzzle was difficult to the point being grotesquely unfair. Still, it sold very well, and continues to sell well. Gordian's Knot a rare "good" too-hard puzzle. The funnest part of a puzzle is fiddling around with it, and this mathematical freak of nature maximized the fiddly fun beyond what was thought possible. I've since heard from many people that have solved it -- at least the "take apart" stage.
It sold well enough, Thinkfun decided to do a sequel. The computers of Frans de Vreugd and others from the puzzle zine Cubism for Fun evaluated *trillions* (with a "t") of possible 6 piece puzzles, and the Z-Knot was the one that ultimately got picked.
I'm not sure if I'll be able to solve it, but I do know I'll enjoy fiddling with it.

We learned about Serpentiles from the grandparents and decided we needed a set for home. It is a great way to interact with your kids, see them solve challenging spatial problems, and enjoy the company of the entire family. We play it during breakfast on the weekends and it makes for a great discussion starter. Give it a go if you enjoy puzzles; you won't be disappointed.

ThinkFun Square By Square Review

My daughter (12) and I like to find new 'car' games. We keep a couple games in the car so when we go out to eat or end up some place where we have to wait, we have something to do. This game is the perfect size and is fun because the two of us can work on it together. It isn't too hard for the kid and just challenging enough to keep my brain occupied.
It is also a good one to play for a while and then put away for a couple months. That way it seems fresh.
Of course I would always like MORE puzzle cards to figure out, but for the price (and free shipping when this was written) - it is great! Cheaper than the store where we first saw it.

ThinkFun Gordians Knot Review

ThinkFun Gordians Knot
Average Reviews:

(More customer reviews)
With many puzzles, a few moves will completely take the puzzle apart. They don't allow much playing around. A successful disassembly may mean that the puzzle is undisplayable and put away, sometimes forever.
Gordian's Knot requires lots of moves to take apart -- over 60 -- more than any simple 6-piece puzzle. Thus, it can be fiddled with and set down again in a perfectly presentable state. Taking a puzzle apart is generally more fun than putting one together. Myself, I have thousands of puzzles, but this is the one that I've played with the most, due to the fact that I don't have to do any clean up when I set the puzzle down again.

An ancient mystery is reinvented for mind-bending, modern-day fun. Gordian's Knot Brainteaser Challenge from ThinkFun is based on the Gordian knot tied by Midas. The Great Oracles proclaimed that the person who solved the puzzle would rule the world. This colorful knot features six interlocking pieces, but it takes a whopping 69 different moves to take the knot apart. By sliding the six pieces past each other, the Gordian's Knot will come apart. Some pieces will easily move throughout the process, but beware -- that doesn't mean you made the right move.
Game comes with a 40-page, step-by-step solution book in case you get stumped, and helps you put the knot back together once the puzzle is solved. For one player.

ThinkFun Clever Castle Review

ThinkFun Clever Castle
Average Reviews:

(More customer reviews)
This game is uniquely designed, and out of the ThinkFun deduction solitaire games, the least sequential. That, plus its visual scheme that encourages youngsters to think in overlaid patterns, makes it excellent for visual-spatial reasoning development.
Typical of the Thinkfun solitaire games, the puzzles are arranged in stages, from easiest to most difficult (four stages for Clever Castle). However, the game only begins to really test deductive skills a few puzzles into the second hardest level, named "Hard". This means that the truly fun challenges are limited to less than twenty total. In fact, the only real drawback I can find in the game is the limited number of levels. It would be nice if ThinkFun would at least offer extra levels, either for free on the web or as a paid add-on.
I would not be afraid to get this game for a child in the 3-4 year old range. They would at least be able to do some of the puzzles, and could grow into the harder ones over time. My 4-year-old was able to finish all 40 levels, though not at one sitting.
