TwinTrix - Twintrix is a mixture between Klax and Tetris
Twintrix is heavily inspired by the Atari ST classic Klatrix, which is a mixture between Klax and 2 player Tetris itself. It's also similar to countless other puzzle games like Columns.
The principle is simple, connect rows of identical tiles to destroy them. A row can be 3 (or more) tiles in any direction and Several rows can be destroyed at once to gain more and more score.
