The Tetrinet ("tnet") concept (as well as Windows client) was developed by St0rmcat. Gameplay is simple: Play a normal
game of
Tetris with the ability to send blocks mischieviously to your opponent in attempt to end their game or to cause some discomfort. The
last man standing is the victor.
If completion of two or more lines is accomplished by a player, the number of lines minus one will be added to his/her opponents.
Standard blocks that can be used during gameplay are as follows:
a - Add line
c - Clear line
r - Random block clear
b - Clear special blocks
n - Nuke (clear) your field
s - Switch your field with an opponent.
o - Block bomb
q - Block Quake
g - Block gravity
However, there exists servers that allow games of "pure" Tetrinet. These games are basically normal games of Tetris against others (the add-line punishment still in play).
NOTE: The above information is based on default server settings. Settings may be changed by the operator of the tnet server. Such options include:
Block occurance
Time limits
Deathmatch settings
Chat between users may be uttered either in the "Partyline" window or during gameplay by pressing 't'. It is customary to say 'gg' ('good game') after each game as a sign of good sportsmanship.
Since tnet's inception, few *nix tnet clients have been developed in order to let the open source community in on the semi-phenomenon that is TetriNet.
Some such clients are gTetriNet (for users of GNOME) and KTetriNet (for, you guessed it, KDE users).
