Cons: The tiles and pins actually don't all stay in their respective positions properly, ie, they can easily fall out in the usual course of playing with this toy. This makes the puzzle more difficult than it needs to be. Also, the numbers start to wear off the pins after just a few days. This toy is marked as ages 6 and up, but I would suggest ages 12 and up.
Unlike other puzzles where you feel as though you are making progress, this puzzle gives beginners the experience of rapidly moving from having all the pieces out - to having "all but one" piece back in, which is not the "correct" piece you were hoping for... but there is no intermediate feedback. I will have to play with it more to see what happens a few weeks into playing, but I can predict that the intense fun most people feel for the toy will wear off within an hour, and 95% of owners will not pick it up again. However, diehard puzzle-lovers will continue beyond this initial phase. I don't really understand the notion that it is educational (in the traditional sense), unless you do what a previous reviewer recommended and remove only the yellow pegs. However, I can't imagine a child who would refrain from pulling out the triangles.
In summary: Totally awesome puzzle for those who *really* love puzzles.
Regardless of where you place the little yellow round buttons, the puzzle can be solved which means there are thousands of combinations of game play. It's all in where you place the white triangular tiles. The ball is about five inches across and is the perfect size to hold in your hand comfortably. The tiles and buttons go in and out easily and stay in the ball securely once you snap them in.
The game uses math and logic skills which makes it ideal for both public schools and homeschoolers. It's fun to play and much more difficult than it sounds. It's totally addicting and I keep picking it up to play just a few more minutes to see if I can solve the puzzle. I manage to get almost to the end of the puzzle before realizing that the tiles are not in the correct places because there are no more tiles whose numbers add up properly. Icosoku is meant for ages 7 to 99 although I would think that a younger child might be frustrated in their attempts to solve the puzzle.
The idea is good, however the design construction is poor. Don't waste your money.
Being a computer nerd, I decided to code an algorithm to solve the minimal pieces for any number of pegs. Is anyone else interested in this? If enough people are interested, I'll deploy my IcoSoKu Solver as a web application. I'm also hoping that, for each peg placed on the sphere, I could quickly calculate and display the number of possible solutions. As you'd drag-n-drop more pegs onto the sphere, that number would keep shrinking. Whenever I determine that only one tile can fit in a particular location, I'd reveal it.
Please let me know if you're interested in such a web app by commenting on this post. I'll update it with any progress I make. (This is just a weekends-and-evenings project for me, so I have no idea how long it will take me).
