.SH NAME
tetris - popular game of dropping blocks.
.SH SYNOPSIS

[-] [-whotnbsa] [-L level] [-N name] [-O oblev] [-K keys]
.SH DESCRIPTION
.B Tetris
is played in real-time on a 10X20 board. Randomly selected shapes of 
four contiguous blocks are dropped from the top of the board. The player
tries to rotate and move the blocks so that they form continuous
horizontal rows. When a row is completed, it disappears. If the screen
fills up to the point that a shape cannot drop below the top of the screen,
the game ends.

.SH DIAGNOSTICS
.I Your terminal must have cursor movement capabilities: 
.br
This is message from the cursor movement package informing you that
your terminal is not sophisticated enough for tetris. In some cases, your
termcap entry might be to blame.

.br
.I Panic!
.br
You have been a naughty tetris player. You have tried to modify your
save file and tetris is now going to punish you.

.SH BUGS
.br
In its current version (1.3) \s-2unix\*R\s+2 Tetris is too cpu intensive.

.br
There are strange quirks that allow blocks to be rotated into one another.

.br
The save game files are minimally secure at best.

.br
The key mapping works but you have to give the keys in the proper order.
The implementation is very unforgiving.

.br
Tetris was conceived by a soviet computer science student and is, therefore,
most probably a communist plot.
