Double Bubble Online Slot


Double Bubble Slot Review
Play the Double Bubble demo for free and try Roxor Gaming's UK fruit machine-inspired slot with a Bubble Line multiplier mechanic active on every spin.
The game runs on 5 reels with 20 paylines. The RTP is 96.02%, volatility is high, and the maximum win is 22,000x your stake from the Bubble Line with all lines active and the logo symbol landing. There are no free spins.
How Double Bubble Plays
Stakes run from 0.01 to 20.00 per spin. The Bubble Line below the main reels is active on every spin and multiplies its symbol's value by the number of active paylines (maximum 22x with all 20 lines). The wild substitutes for all standard symbols on both the main reels and the Bubble Line.
The Bubble Popper bonus triggers when the bonus symbol lands on reels 1, 3, and 5 simultaneously. You pick bubbles to reveal cash prizes. No free spins round is available; all bonus value comes from the two core mechanics.
Symbols and Payouts
Standard symbols include fruits, golden bells, a blue 7, and BAR icons. The Double Bubble logo is the highest-paying symbol and generates the maximum Bubble Line win. The wild substitutes for all standard symbols and can land on the Bubble Line.
The bonus symbol on reels 1, 3, and 5 simultaneously triggers the Bubble Popper pick-me game. The Bubble Line symbol is randomly assigned each spin from the standard set.
