The main objective of Side Pocket is to sink balls in each level and reach predetermined scores to progress. However, with only several "lives" available, any error can be fatal. After completing each stage, a bonus stage will appear, offering the chance to earn extra balls and a better target in the parquet block.
The Side Pocket game has undergone various changes across different platforms. The original Arcade version is a pool game where the player competes against the timer, trying to get all balls into pockets and earn points. On the NES release, modes were introduced for 2 players, including 2P Pocket Game and 9-Ball Game.
The game has been released on several platforms, including the Game Boy, Genesis, and SNES. The Game Boy version features a completely redrawn game with 1 or 2 player actions in two game modes: 9-ball and Pocket. In contrast, the Genesis and SNES versions feature improved graphics and sound, with a reworked Pocket game mode that includes more stages and trick shot layouts.
The Side Pocket Game Gear version is similar to the Genesis version but with toned-down graphics. A notable release for Wonder Swan features one and two-player play on a single device, with the player choosing an avatar from a menu and competing against opponents in a single-player mode.
