Intelligent TETRIS (ITETRIS for short) is another implementation of the classic game that could hardly impress anyone, apart from a minor feature: ability to play itself. Yes, it can think! In demo mode, it does not follow a predesigned scenario, it does not even select a convenient tile: the tiles fall in usual random way.
GTetrinet is a clone of the popular Windows game Tetrinet. It is designed to be fully compatible with the original Tetrinet, as well as being identical in gameplay. There is theme support and Spectator support on Tetrinet-X servers with the qirc patch by Drslum.
