Probably the most famous and the most suitable for the definition of "classic" puzzle, where you need to "catch" falling/sliding blocks of various colors and then to create from them a variety of ranks and diagonals.
Each level has a specific task, as you progress through levels the difficulty increases, colors become more, the speed of the falling blocks above. The game supports three graphics card is better (even from the point of view of the ability to distinguish colors) – of course, the VGA version.
A classic of the genre.
