Archibald's TriTris 1.0   
by Archibald The Cat entertainment   

Archibald's TriTris is a clone of world-famous Tetris, based on
lining up tiles of the same color.
Amusing and easy-to-play choice for everyone who wants to try
something new. Non-violent arcade game for kids, adults, home or office.
You are to line up three or more tiles of the same color horizontally,
vertically or diagonally. Triplets of the same color are erased,
freeing space for the next bar falling down. The game ends by
filling up the game field in arbitrary column.
