The game consists of a black plastic case and multi-colored balls, which have a variety of forms.
In a little book some of these parts are the original game. The rest you have now so put in a case that no match partial remains.
There are various levels of difficulty, with the most simple you have to place only one token, the most difficult but you have to align the majority of the pieces correctly to get to the solution.
The higher the degree of complexity the longer the tinkering. With practice, however, the solutions can be found more quickly.
What unfortunately somewhat bothers me is the smallness of the product. The case, the game pieces and the book falls but from very small, so I would not recommend people with a visual impairment.
I use this kind educational toys happy for my neurological patients in the hospital, but I can not use at all this game because it just turns out rather small.
