To play Tetrinet, you first need to find a server where you can connect. You may try the servers at
http://www.tetrinet.org/ or create your own using tetrinetx (a UNIX server, not included in this
package).
Once inside a server, you'll be able to communicate with other players using the PartyLine tab, see the
server's highscores in the Winlist tab and the actual game in the PlayingFields tab. You can switch
between the three tabs using the Alt+1, Alt+2 and Alt+3 shortcuts.
Tetrinet is like Tetris, but multiplayer and with some additions. The goal of the game is to remain
alive, by filling up other player's fields. There are some special blocks that can be used for your own
benefit and against other players. They will appear randomly in your field, replacing previously existing
blocks when you complete a line. You'll gain special blocks when you complete a line that contains one.
It will be added to your inventory, which is just below your playfield. You need to use them in the order
you collect them, by pressing the number of the player you want to use it against. For example, if your
active block is "Add Line" and you want to use it against Player 3, you'd have to press "3" and Player 3
would get a line added in that instant. The following blocks are available:
Ablock
Add Line will add an incomplete line to the bottom of the selected player's field.
Bblock
This will remove all the special blocks from a player's field.
Cblock
Clear Line is the opposite to Add Line; it will remove a line from the top of the selected
player's field.
Gblock
The Gravity block may be very useful if applied to a field which has lots of unfilled
spaces all around. Blocks over them will fall into the gaps, making the puzzle collapse
significantly.
Nblock
Nuke will clear the chosen playing field completely, as if they had just started the game.
It's useful to help team mates or when you are about to lose.
Oblock
Block Bomb will clear 3x3 portions of a player's field where there are other O blocks. The
blocks in the 3x3 area will get scattered anywhere around the field.
Qblock
Quake will make each of the lines in a player's field shift to the left or right, or stay
as they were.
Rblock
Random will remove 10 random blocks from the selected player's field.
Sblock
Switch allows you to swap your playing field with another player. This can be a deadly
block if used with a bit of strategy.
