netris(6) networked version of tetris


netris [-wFDSCHR] [-c host] [-p port] [-k keys] [-i sec] [-r robot] [-s seed]


The object of the game Tetris is to fit the shapes together forming complete rows, which then vanish. When the shapes fill up to the top, the game ends. This version of Tetris can be played against other people over a network.

Two player mode

It's just like normal Tetris except that when you clear more than one row with a single piece, the other player's board is moved up and junk rows are added to the bottom. If you clear 2, 3 or 4 rows, 1, 2 or 4 junk rows are added to your opponent's board, respectively. The junk rows have exactly one empty column. For each group of junk rows given, the empty columns will line up. This is intentional.

The longest surviving player wins the game.

One player mode

This mode is currently very boring, because there's no scoring and it never gets any faster. This will be rectified at some point. I'm not very motivated to do it right now because I'm sick of one player Tetris. For now, use the "f" key (by default) to make the game go faster. Speed-ups cannot be reversed for the remainder of the game.
