Timberdoodle's review
Watch the video and see how to play IcoSoKu.

Endless possibilities, endless opportunities, endless fun; IcoSoKu is a brilliant mathematical brainteaser with unlimited challenges.
Place IcoSoKu number buttons randomly around the surface, then match the dotted tiles to the numbers. The dots on the IcoSoKu tiles surrounding each number button must add up exactly to the number on the button. You've succeeded when you've placed all the dotted tiles correctly so the numbers match the surrounding dots, with no dotted tiles left over.

IcoSoKu is a terrific 3-D puzzle for your beginning mathematician. Reinforces counting, addition, and thinking skills. IcoSoKu is sure to become a homeschool favorite! For ages six and older.
