Block Attack - Rise of the Blocks is a puzzle/blockfall game.
In Tetris, the blocks fall from the sky. In Black Attack - Rise of the Blocks, the blocks come from underneath, and scroll upward. The speed of the blocks get faster as the game goes on. You know how it works—games like to punish you for doing well!
To eliminate blocks from the stack, line up at least three of one color, horizontally or vertically. Once you do, those blocks explode and disappear, reducing the number (and height) of the blocks still on your screen.
