Blox

Blox is a 1-player Tetris clone for the TRS-80 CoCo.

The player tries to position different shaped 4-square blocks as they fall from the top of the screen. If the player fills a row, that row is removed, and the player scores points. If the blocks reach the top of the screen, it's game over. There are 10 levels of difficulty, and the player can start with 1 - 4 rows of random blocks.
