If I had known, I would have bought a copy for each of the family !!!!

Originally bought for my youngest daughter, this game was so successful that everyone snatches at home to play (including dad!).
The game, travel size (the size of a smartphone), is composed of geometric shapes (small balls linked together to form different shapes) and the goal is to assemble them to completely fill the playing board (game 2D) or to make a pyramid (3D game).
It comes with a manual that includes 101 combinations that range from simple to more complicated. The simplest combinations indicate the place of all rooms except one (the level can play my younger 4 year old daughter) and as and difficulty, we must guess instead of more coins. For the pyramid, the principle is the same except that the pieces can be placed horizontally or vertically (on different levels of the pyramid).
This game is very addictive, even (especially ???) for adults. I think also try the other brand models (so that there is more at home tussle over who will play or not!)
