LegTris is a portable, no installation, Tetris clone that uses Lego blocks as the game pieces.

The game plays exactly like Tetris on your computer. There is no manual, and no description, so you're on your own but here's all you need to know that we found with a little trial and error.

Use the left and right arrow keys to rotate the pieces and the down key can be held to drop or tapped to speed up the descent. Hit space to jump to the next brick. Each piece has a shadow that fades as the brick gets closer.

P will pause the game and ESC quits the game.
