.TH XTETRIS 6 "11st May 1989"
.SH NAME
xtetris \- X Window block dropping game
.SH SYNOPSIS
.B xtetris
[
.B "X options"
]
.SH DESCRIPTION
.I Xtetris
is a game involving dropping blocks. As they drop you can move them to
the left or to the right by clicking the left or right mouse buttons
respectively. Pressing the shift key while clicking the button causes
the falling shape to rotate anti-clockwise (left mouse button) or
clockwise (right mouse button). Pressing the middle mouse button causes
the shape to quickly drop. Note that the mouse must be in the window in
which the shapes are dropping for these actions to work correctly.
.PP
You can also use the keyboard: j for moving to the left, l for moving to 
the right, k to rotate anti-clockwise and space for dropping quickly..
.PP
Points are scored for each block that comes to rest on the gradually
building up pile of blocks. Different blocks in different orientations
have different point values. When the pile reaches the top of the
screen and no further blocks can be dropped the game ends. Whenever a
full row of blocks across the screen is all completely filled in that
row is removed and all the blocks above it drop down a further row.
As more rows are deleted the blocks drop faster.
.PP
A high score table is kept which is retained between separate executions
of the game.
