Blockdown
Description
Blockdown is a Tetris clone for multiple systems.
Geometric shapes fall from the top of a playfield to rest on the bottom of the screen; fit the pieces together, and the line they form disappears. If the pieces don't form lines and eventually stack up to the top of the playfield, the game is over.
The upcoming six pieces are shown in the top left corner of the screen. Every 10 lines completed raises the difficulty level. Difficulty increases by dropping the pieces faster and faster over time.
