NAME
xtetris - X Window block dropping game
SYNOPSIS
xtetris [ X options ]
DESCRIPTION
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.
You can also use the keyboard: h for moving to the left, l for moving to
the right, j to rotate clockwise, k to rotate counter-clockwise and space
for dropping quickly..
You can also use the direction pad, if your keyboard has one: (Left) to
move left, (Down) to rotate clockwise, (Up) to rotate counter clockwise,
and (Right) to move right.
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. When a row of blocks
across the screen is completely filled, that row is removed and all the
blocks above it drop down. As more rows are deleted the blocks drop
faster.
A high score table is kept which is retained between separate executions
of the game. You can avoid recording your score, by using the -noscore
option.
Xtetris requires the installation of an application defaults file,
probably in the file /usr/lib/X11/app-defaults/Xtetris. If that file
does not exist, xtetris cannot run. (It will probably print out
something like "Width zero. Terminating.") Almost everything about
xtetris can be configured in your .X11defaults file. You can use the
application defaults file as a guide.
OPTIONS
Xtetris takes standard X options (see X(1)). It adds the following:
-boxsize boxsize
Specifies the width of the square blocks that compose the falling
objects. The overall size of the game board adjusts to boxsize.
-noscore
Runs xtetris without recording your score, or showing you the
score file when you have finished the game.

-score Runs xtetris using the scorefile, if it exists.
-speed speed
Sets the game's speed. By default speed is 10. 20 causes the
game to be 2 times faster, 5 makes it 2 times slower. "-speed
50" makes for an extremely fast game, however you will need a
fast processor to support it. Keep in mind that as you knock out
rows, the game's speed increases. If you set your speed below
the standard of 10, your score will not be recorded in the score
file.
-color
-bw Determines whether to use the color or black-and-white
application-defaults file. This sets the new X11R5
"customization" resource to ".c" or ".bw", depending on your
choice.
FILES
/usr/lib/X11/tetris_scores
/usr/lib/X11/app-defaults/Xtetris
/usr/lib/X11/app-defaults/Xtetris.c
/usr/lib/X11/app-defaults/Xtetris.bw
Top 10 high scores.
ENVIRONMENT VARIABLES
XTETRIS
If set, your desired name for the high score table.
BUGS
A bug in X11R5 makes the /usr/lib/X11/app-defaults/Xtetris necessary:
the pop-up score-box and about-box do not get a propagated
"customization" resource.
