Double Bubble FAQs
How to Play Double Bubble?
The Double Bubble slot showcases a straightforward play style. Upon loading into the game, you can adjust the number of paylines and the bet stake using the options near the bottom-left of the screen. Then, you can tap the spin button on the right to set the reels in motion.
Step 1: The Basics
When loading into Double Bubble, press the + and + in between the "Lines" button to adjust the number of paylines from a maximum 20. You can also adjust the bet stake by using the + and - arrows that surround the "Coin Size" button.
After selecting your bet stake, simply tap the rectangular green spin button near the right-hand side of the screen to start playing.
Step 2: How To Play
Once the spin button is pressed, the 5 reels spin and then randomly come to a stop.
In Double Bubble, landing at least 3 matching symbols on any of the 20 paylines starting from the leftmost reel forms a winning combination. Alternatively, landing 2 Wilds, 2 Super 7, 2 Bell or 2 triple BAR symbols can also lead to a winning combination. After a spin, successful matches are highlighted, and winnings are immediately added to the player’s balance.
Symbols that land within a bubble get added to the Bubble Line; their payout values get multiplied by a stake multiplier. This then gets paid to the player.
