This is such a wonderful two player game for any age. A Tetris-like zen experience building a quilt and trying to accumulate the most buttons with the least blank spaces at the end. A nice, easy light game that I highly recommend.
The goal is to have the most buttons at the end of the game so you'd think the best strategy would be apparent but it's not that simple. The multiple ways you can gain or lose buttons will make you question every move. You'll want to play several games at a sitting just figure out the best strategy, but it's illusive.
