pool/snooker/carrom/hockey/curling simulator for X11

 Especially the billiards variants are very playable and nice. The only
 drawback is that there are no rules implemented so you have to know them
 yourself :-)
 .
 NOTE: The game will only run on a screen with 8 bit color depth (256 colors);
 displays with a color depth above 8 won't work. You've got to switch to
 a 8 bit display before playing the game or with XFree4.0 you could use
 an 8 bit overlay if available. The original author has abandoned the game
 so it's unlikely that the color depth problem will get fixed anytime soon. If
 you are able to fix the game for other depths please send the patch.
