Bubble Shooter Candy 3 is a match-3 bubble-shooting game set in a world filled with candy. The player attempts to repeatedly clear a blue-purple playfield of rows of shiny, colorful bubbles that look like slightly flattened, hard-candy disks before the shapes slide below a horizontal line near a points-reward area marked 50 | 100 | 250 | 100 | 50.
The player shoots candy projectiles from a shooter. The weapon holds two candies at a time. The player can switch projectiles to use one that best matches the available bubbles on the bottom rows, but the player can only perform this action three times for free. Afterward, they must watch advertisements to use it.
The game requires the player to shoot at two or more connected candies of the same color. They can use a targeting line made of dots to help them pick the perfect angle for each shot. When the candy bubbles fall, they hit the points-reward area and burst or turn into stars and disappear. The player earns the most points from combination moves in which they take out a group of bubbles or lines in a streak.
Bubble Shooter Candy 3 features a swirled rainbow booster candy that the player earns via combo play. The projectiles take out candies of any color.
The game also tracks the player's last-best score so they can attempt to beat it the next time they play.
