Lunar Pool (known as Lunar Ball in Japan) is a rough simulation of pool (pocket billiards) combined with aspects of miniature golf, created by Compile for the Nintendo Entertainment System, in which each stage is a differently shaped pool table. The object is to knock each ball into a pocket using a cue ball. There are sixty levels to choose from, and the friction of the table is adjustable.
