.SH DESCRIPTION
.B xtserv
is the server for the synchronous multi-user version of Tetris,
.B xtris.
.B xtserv
listens for connections on a TCP port, keeps an internal list of
connected clients, and broadcasts information among clients to
manage starting the game, setting the level and mode, as well as
seeing each other's screens.
.B xtserv
is started automatically by
.B xtris,
with the option '-once', if
.B xtris
does not find an
.B xtserv
running on localhost, and no server host has been specified.
.B xtserv
will automatically restart a game when the one-but-last
player has lost, unless started with the option -norestart. It will
not automatically restart a game if the user is playing alone.
.B xtserv
will also drop all bots when there are only bots left in the game.
The server can handle
clients exiting, being killed or losing the connection even in the
middle of a game.
Killing an
.B xtserv
will cause all connected clients to exit.

.BR xtbot (6)
