Connect the Bubbles is a match-3 bubble puzzle game that requires a player to strategically link three or more bubbles of the same color to clear a game board and earn points while competing against other players to earn the highest score. To make linking more difficult as the game progresses, the shape of the board changes along with the number of bubbles. The game also times the player by limiting moves. It displays the remaining moves per game above the board.
The player receives access to special bombs, rockets and color boosters to help them clear away bubbles faster. Whenever the player performs certain types of moves, they earn extras. For example, they earn an extra bomb when they clear a chain in the shape of a square, a rocket for 10 or more linked bubbles and a color booster for one long chain made of every bubble of the same color.
The game displays the players score at the top left corner of the board and a left-shifting leaderboard at the center with the scores and pictures of players in proximity of the player's position and gift boxes. The player receives extra points, boosters and moves when they bypass the scores of other players. They also receive extra boosters after they play a certain number of games.
