Idea of the game is to stack bricks up in such a way that bricks of the same type form columns, rows, or diagonals of three or more items. Each level has its mission, for example, to make 16 diagonals, etc. Use cursor control keys to:

up - swap the bricks in the set as they fall;
left, right - to move the set of bricks as they fall;
down - immediate drop of the set of bricks down.

In the end, you can engrave your name and record in the table (Save) or continue the game (Play).
