20,000xMax WinThree moments define a round on the reels — from the base 5×3 grid to the Bubble Line multiplier and the Pop the Bubble bonus.
5 reels, 3 rows, 20 fixed paylines: match classic fruit-machine symbols — cherries, grapes, bell, orange, watermelon, BAR tiers and Super 7 — left to right for a payout.
Any symbol that lands enclosed in a bubble is copied onto a secondary Bubble Line under the reels. A win there is multiplied by the number of paylines in play, up to 22x at max bet.
Land 3 Bonus bubbles on reels 1, 3 and 5 to pop them for instant cash prizes, while the Double Bubble Wild substitutes for everything else. Maximum win: 20,000x the stake.
The 5×3 grid keeps the base game simple and instantly familiar, while the Bubble Line and Pop the Bubble bonus add the extra layer that's kept this Gamesys classic running for years.
The Wild substitutes for every regular symbol to help complete winning combinations, with five Wilds on a payline paying the game's top prize.
Three Bonus bubbles landing on reels 1, 3 and 5 trigger a pick-a-bubble round for instant cash prizes.
Real screens from the interface — the base grid, a Bubble Line win in progress, and a jackpot-meter variant some operators run.
Double Bubble runs directly in the browser on desktop, tablet and phone, with no app to install. The reels, bet panel and Bubble Line stay sharp and easy to read at any screen size.
Double Bubble's paytable runs from classic low-paying fruit up to BAR tiers, Super 7 and the Bell, topped by the Double Bubble Wild — with the Bonus bubble working purely as a feature trigger.
