Double Bubble

About Double Bubble

Double Bubble is a 5-reel, 20-payline fruit machine slot built around a Bubble Line that runs under the reels on every spin. It was first released by Gamesys as an in-house title for the Jackpotjoy and Virgin Games platforms, where it became one of the most-played games on UK bingo sites for years before reaching mainstream casinos. The studio later rebranded as Roxor Gaming and was acquired by Aristocrat Interactive, which is why the game now sits under the Aristocrat banner.

The look is deliberately retro: pastel bubbles, classic fruit symbols, and a clean paytable. Underneath that simple surface sit two bonus games and a Bubble Line mechanic that can attach multipliers to wins. The result is a game that reads as a traditional fruit machine but pays out through a few features players will not find on older cabinet slots.

How to Play Double Bubble

Set your stake using the bet controls, then spin the five reels. Wins are formed by landing three or more matching symbols across any of the 20 paylines, running left to right. The lower-value symbols are the classic fruits (cherries, plums, grapes, melons), with bells and the Double Bubble logo paying more.

The Bubble Line is in play on every spin and can apply a multiplier to a winning line, which is where a lot of the base-game value comes from. The Wild substitutes for standard symbols to help complete combinations. Stakes at Midnite start from £0.01 per spin.

• Wild symbol: Substitutes for standard paying symbols to complete winning combinations.

Double Bubble Theme and Symbols

The theme is a soap-and-bubbles take on the classic fruit machine. The background is a pale, washy green dotted with floating bubbles, pipework and clouds, and the reels carry traditional one-armed-bandit symbols rendered in a soft, cartoonish style. It is closer to a nostalgic arcade cabinet than a modern cinematic slot, and that is the point.

Symbol-wise, the cheaper wins come from cherries, oranges, plums, grapes and melons. Bells and the Double Bubble logo sit at the top of the paytable. The Bubble symbols tie into the Popper Bonus, and the Wild rounds out the set.
