Tetcolor
Tetcolor is an action puzzle game released in 1991 for DOS. Developed by an unknown programmer, it is a color-based variant of Tetris where players rotate and position falling blocks to create matches. Rather than clearing complete lines, the objective is to match three or more blocks of the same color to eliminate them from the playfield. The game employs keyboard controls for movement, rotation, and piece acceleration. As players advance through levels, the falling speed increases and more complex color patterns emerge. Scoring rewards both the number of blocks cleared and consecutive matches, with bonus points for larger groups eliminated in rapid succession. The progressive difficulty ensures gameplay remains challenging as new mechanics and piece types are introduced.
