Polar Bear Merge is a bubble-shooting game that combines connect and tile-merging play. A polar bear on an ice floe needs the player's help to remove rows of hanging ice balls before the balls slide down the screen past a horizontal timer liner above its head.
The player can't use match-3 mechanics, as seen with other bubble shooters. Instead, they direct the bear to toss balls labeled with numbers at one or more matching balls to force the balls to merge together. The connected balls merge upward toward the end of the connection. Balls below connected balls drop onto the timer line and break to disperse points.
The polar bear primarily throws ice balls labeled 1, 2 and 3. When these balls strike matching balls, the connected balls create a ball with the next-highest number. For example, if a 2 ball hits one or more 2 balls, all connected 2 balls merge to form a single 3 ball. If the ball forms next to one or more 3 balls, the balls merge to create a single 4 ball.
Polar Bear Merge rewards the player with points and coins. The player uses coins to purchase different colors and shapes of ice. If they're willing to watch an advertisement, they can double their coins.
The game also offers the player a rocket booster and a 10-second stop-time booster. That said, the player must watch ads to use these helpful tools.
