Double Bubble Bonus Features

Game Symbols

A total of 10 regular symbols are featured in Double Bubble. Let’s start with the low-end. The cherry, the watermelon, the grapes, the orange, and the plum represent the low-paying symbols in Double Bubble. The cherry, the watermelon, and the grapes have a max payout of 100x, while the orange and the plum have a max payout of 200x. 

The red, blue, and green bar, together with the bell and the Super 7 are the high-paying symbols in the game. All of them have a max payout of 500x.

A Wild and a Bonus symbol are also featured in the game. The Wild can replace any regular symbol, but it also can bring a massive reward to the players. It has a max payout of 20,000x.

Bonus Rounds & Free Spins

In Double Bubble, the Bonus symbol does not reward players with Free Spins. Instead, if the player lands 3 Bonuses on the first, third, and fifth reel, the Bubble Popper Bonus will be triggered. This bonus lets you pop a bubble to win a prize. The wins are multiplied by the bet amount. 

The Bubble Line bonus also deserves a mention. All symbols appearing in a bubble are placed on the Bubble Line and multiplied by the Bubble Line Multiplier. The Bubble Line Multiplier is increased to 22x when 20 lines are played.
