Bubble Fish is a fun bubble shooter that features a sea or aquarium theme. The backdrop of the playfield displays blue water with coral, shells, sponges, seaweed and crabs. The game displays a mix of colored bubbles filled with fish or shells in rows that rapidly shift down the screen.
The player's goal is to earn points by creating links of three or more identical bubbles using a projectile bubble fired from a shooter that features a spear as a pointer. They win a level by collecting a specific number of certain types of bubbles displayed in a task area on the right side of the screen.
Unlike similar games, the player doesn't receive a targeting line or preview of upcoming projectiles to help them make matches faster. The game also delays revealing the projectile. The player must then quickly determine if the bottom of the rows contains a bubble that matches the projectile and links to at least one other matching bubble.
A player can spend hours enjoying dozens of Bubble Fish levels. During play, they can review the level number and current score on the left side of the screen. After they win a level, they receive both their level score and their all-time total. If they lose, they must watch an advertisement to keep their current game going with the same points or start over.
