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 Hot Spot Review

ThinkFun Hot Spot
Average Reviews:

(More customer reviews)
We got this for our 6 year old but it is too hard for her. I think our 10 year old will like it more, if we can get her to try it.
I love how the game is self-contained- the game board serves as the case. So it would be good for travelling and easy to store. All of the components are very well made.
My only complaint are the cryptic instructions. My wife gave up on figuring out how to play so I gave it a chance. It took me almost an hour. We both have college degrees, so it's not like we're lacking in the brain department.
Overall the rules are simple; here are some clues that would have saved us some time...
-The pieces are only numbered for the sake of the solution instructions on the back of the cards
-all pieces can jump any way at any time, except diagonally and not when two large pieces end up next to each other
-the solution instructions on the back of the cards say the piece number (1-9, or X), and what direction it should jump, so "1R, XU" means to jump piece 1 to the right, and then jump the red X piece upwards.

ThinkFun Pete's Pike Review

ThinkFun Pete's Pike

I gave this game to my kids for Christmas..on Christmas day, family members were sitting around for hours playing it. After we got going, the only time we stopped was to eat. When the kids saw the adults playing it, they lost interest in the other toys to see what we were doing. We all like this game, today I'm picking up a couple more for the other family who were playing it. It ranks right up there with Rush Hour in my opinion...both are great games.

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.

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.
