The game combines pool (pocket billiards) with aspects of miniature golf.

Lunar Pool was distributed by Pony Canyon in Japan and Fujisankei Communications International for the rest of the world.

Completing a level awards one extra life, or two if the player has pocketed at least one ball on every shot.

The game ends after all lives are lost or 60 levels have been completed, whichever occurs first.

The game includes an adjustable friction setting, which determines the rate the balls slow down after being hit, as if affected by different amounts of gravity (thus the lunar reference in the title, along with Moon-related background imagery within the game).
