Pros: If you write down the positions when you first get it, at least you can return the puzzle to a solved state easily. It's fun to click the pieces in and out, even if you don't end up with a solution. It's visually very attractive. It makes for "family fun" over the holidays as everyone has their turn at not being able to solve it.

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.

Icosoku is a hand held sized ball that holds movable number buttons and triangular tiles. The round yellow number buttons range from one to twelve. There are twenty white triangular tiles that contain different numbers of dots in each corner. The idea is for you to match the white, triangular tiles so that their corner numbers add up to the round yellow number buttons that they surround. Each round yellow number button will be surrounded by five different triangle corners. Some of the corners are blank to make the number additions possible.

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.

This is a great toy/game for anyone who loves Soduku, logic puzzles or things like a Rubik's cube. It is absolutely addicting!!!! We opened it up on Christmas Eve, and could not put it down. We ended up staying up most of the night working it out. And don't be fooled into thinking you'll figure it out easily, you won't. It's alot harder than it seems at first -- or tenth -- glance. Buy it and you will NOT be disappointed!

It came quickly. Was what seller said it was. It was in good condition. The only problem I had is probably my fault. The families I gave them to had children ages 11, 13, and up to 17. They became bored with them very quickly. I thought it would be a fun way to practice math skills, but the kids were already farther advanced mathematically to get much of a challenge from it.,

While this game is fun and very challenging, the only directions were on the box which got thrown away with our other Christmas garbage. My 11 year old likes it but he gets pretty frustrated with it after about 10 minutes.

Less than a week after Christmas, this educational toy is bagged for trash. After quickly solving the configurations, the entire ball came apart and is impossible to put back together. We have all tried.
The idea is good, however the design construction is poor. Don't waste your money.

Firstly I love the toy, BUT I gave it 3 stars because it was physically impossible to solve UNTIL I realized what was wrong, it came with 2 number "6" pegs and to solve the puzzle you need one of each peg, 1-12. Once I began treating one the number "6" pegs as a number "9" peg I had no trouble solving the cube in about 5 minutes with ease.

This is really fun (I love it as much as the kids) My only peeve is that the pieces don't fit as snuggly as they could and fall out sometimes when trying to figure out the puzzle. I would definitely recommend !
