Draw on a newly-created window. This is the default.

Draw on the specified window.

--mono

If on a color display, pretend we're on a monochrome display.

Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

--clock

The score of the game will be the current time.

--noise float

How noisy the video signal should be (between 0.0 and 4.0 or so).

--fps

Display the current frame rate and CPU load.

(-p1 | --p2) mode

Set a player to either ai, mouse, tablet, kbleft (for W and S), or kbright (or just kb, for arrow keys).

ENVIRONMENT¶

DISPLAY

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

XSCREENSAVER_WINDOW

The window ID to use with --root.

X RESOURCES¶

Notable X resources supported include the following which correspond to standard TV controls: analogTVTint, analogTVColor, analogTVBrightness, and analogTVContrast. They range from 0 to 100, except for tint which is an angle between -180 and +180.
