Double Bubble slot overview
Let’s take a closer look at the Double Bubble slot.
Design & graphics
One peep at this game shows that Double Bubble’s design is both nostalgic and charming.
🍒 The reels are set against a pink console reminiscent of a vintage fruit machine, with glossy fruit symbols such as oranges, grapes and melons. The pretty-prink bubblegum theme ties everything together with fizzy, cheerful visuals.
Whilst the graphics are deliberately simple, this retro aesthetic appeals to players who prefer a straightforward slot without unnecessary extras. Simply put: no muss, no fuss.
Game developer
Originally created by Gamesys, Double Bubble is now part of the Aristocrat portfolio after a series of acquisitions.
Gamesys has a strong reputation in the UK market, having produced hits like Secrets of the Phoenix and Tiki Island. The studio is known for slots that combine simple gameplay with rewarding bonus features, and Double Bubble is no exception.
RTP & volatility
The Double Bubble RTP (return to player) sits at around 96.02%, which is competitive compared with other online slots.
Double Bubble is considered medium to high volatility. This means payouts can be larger but less frequent, making bankroll management and responsible play important for longer sessions.

How does the Double Bubble slot work
Whilst researching for this Double Bubble review, we found that the slot’s gameplay is pleasantly straightforward.
All you have to do is: Select your coin size, choose how many lines to bet on (from one to twenty), and hit spin. Betting on multiple lines increases your chances of landing a winning combination, but your coin value determines the size of payouts.
Wild symbols, represented by the Double Bubble logo, can substitute for other symbols to create winning lines, with five Wilds across a payline awarding the maximum prize of 20,000x.
Double Bubble might have a retro simplicity, but don’t underestimate the game’s bonus rounds. Here are the main events:
Bubble pop bonus
Trigger the Bubble Pop Bonus by landing Bonus symbols on reels one, three and five.
You will then choose one of three bubbles to pop, each containing a random multiplier applied to your stake. Sweet!
Bubble line bonus
Unique to this slot, the Bubble Line runs beneath the main reels. If a symbol lands encased in a bubble, it moves down to this second win area.
Any winning combinations along the Bubble Line are multiplied by the number of lines you bet on, up to a maximum of 22x when all lines are active, adding a fresh twist to the classic slot style.
Bonus pays
Bubble Line wins do not just mirror the main reels. They also pay out with an added multiplier, giving you another route to land sizeable wins alongside standard paylines.
Free spins
Double Bubble free spins are sometimes offered by casinos as part of promotions rather than built directly into the game.
