Quadz

Quadz is a Nintendo Entertainment System port of the game Squarez. You get a random
3×3 tetris-like piece, and have to place it somewhere in your game area before the timer
runs out!.

When you form a completely filled 3×3 square it is removed from the game area. The
more you get at a time, the more points you get!.

When playing against an opponent, clearing large areas will move the dividing wall
closer to their side, making your inevitable victory that much closer.
