Double Bubble Slot Review: The Bubblegum Classic Behind a UK Bingo Empire
Published: October 2020 | Reviewed by the SlotsLike editorial team
Double Bubble sits alongside Chibeasties 2 and Celebrity in the Jungle for feel and features. Made by Gamesys (Roxor Gaming) — Bally’s Corporation, Double Bubble pairs 5 reels and 3 rows with 20 paylines and an RTP of 96.02% — variable (approx 95.75%–96.24%) at some operators, check before playing. Close matches to Double Bubble on gameplay include Celebrity in the Jungle and Cosmic Fusion. On the bonus side you get increasing multipliers. Smaller wins come around often, so the balance moves more smoothly.
Few online slots are as woven into UK gambling as Double Bubble. It became Gamesys’ signature game and a permanent fixture on bingo and casino sites like Jackpotjoy and Virgin Games — so popular that owner Bally’s named an entire licensed brand, Double Bubble Bingo, after it. The appeal is not depth; it is the steady rhythm of small wins and the jolt when symbols drop onto the Bubble Line. If you are looking at slots like Double Bubble, you are almost certainly after that same easy-going, low-stakes, frequent-hit experience rather than feature-heavy modern design.

Double Bubble Pros and Cons
Reviewed by Paul StonePublished: January 2019
Why this dated classic keeps UK players coming back — and where it falls short.
| Pros | Cons |
|---|---|
| The Bubble Line is the whole game in one mechanic: land winning symbols on that special line and the payout is multiplied up to 22x — the single feature that lifts a quiet fruit win into something worth watching. | Mechanically thin by modern standards — one multiplier line and a basic pick bonus, with no free spins, no cascading reels and no bonus buy to chase. |
| Low-to-medium volatility with frequent small hits, which is unusual for a slot that still carries a 20,000x ceiling — it suits casual and bingo-site players who want regular action over big swings. | The 22x multiplier only applies when wins fall on the Bubble Line specifically, so the genuinely big payouts remain infrequent despite the gentle variance. |
| It is available at UK Gambling Commission-licensed operators such as Jackpotjoy, Virgin Games and Double Bubble Bingo, so UK players get full regulatory protection and GAMSTOP coverage. | The RTP is variable — operators can run versions between roughly 95.75% and 96.24% — so the headline 96.02% is not guaranteed on every site. |
| Stakes start from as little as a penny, making it one of the more genuinely accessible classic slots for low-budget play. | Outside the Bubble Line, base-game wins are small, so stretches between multiplier hits can feel flat. |
| The Bubble Bonus is refreshingly transparent — you simply pop bubbles to reveal instant cash, with none of the convoluted multi-stage rules newer slots pile on. | The retro bubblegum look and sound feel genuinely old beside modern releases, and the theme won’t be to everyone’s taste. |
How Double Bubble Works
Double Bubble is a five-reel, three-row slot with 20 fixed paylines that pay left to right from reel one. Mechanically it is a classic fruit machine at heart, but its defining structural quirk is the Bubble Line — a highlighted horizontal line running across the reels. When a winning combination lands on the Bubble Line, that win is boosted by a multiplier that can climb to 22x. Everything else about the base game is deliberately straightforward: set your stake, spin, and watch the lines. There are no cascades or ways-to-win here, which is exactly why slots like Double Bubble appeal to players who find modern releases overcomplicated.
The Bubble Wild substitutes for standard symbols to help complete combinations, and the game’s bonus is reached through the bubble symbols rather than a scatter-triggered free-spins round.
Symbols and Paytable
The reels are stocked with classic fruit-machine iconography given a bubblegum twist — bars, lucky sevens, bells and fruit symbols, topped by the bright Double Bubble logo as the premium and wild symbol. Wins are formed by matching symbols left to right across the 20 paylines, with the logo paying best and the fruit and card-style symbols filling out the lower tiers. The numbers are modest until a win lands on the Bubble Line, where the multiplier does the heavy lifting.
The Bubble Line and Multiplier
This is the mechanic that gives the slot its name and its identity. The Bubble Line is a specific line across the reels; any winning combination that lands on it has its payout multiplied, scaling up to 22x. Because the multiplier is tied to that one line rather than every win, it creates a clear focal point on every spin — you are always watching to see whether your win has landed where it counts. It is a simple idea, but it is the difference between a forgettable small win and the kind of payout that keeps Double Bubble on UK bingo sites year after year.
The Bubble Bonus
Double Bubble’s bonus round is a pick-and-pop game: you are presented with a screen of bubbles and choose which to burst, each revealing an instant cash prize until you hit a collect. It is short, transparent and entirely luck-based — no skill, no multi-tier ladders, just the satisfying pop of revealing a prize. Some Gamesys sites have also attached a network jackpot to the game over the years, though availability of any jackpot depends entirely on the operator, so check before you play if that is what you are chasing.
Our Verdict
Double Bubble is a comfort-food slot, and we rate it honestly as one. It will not impress anyone hunting for free spins, big multiplier ladders or 50,000x potential, and the presentation is showing its age. But the Bubble Line multiplier still delivers a genuine spike of excitement, the low-to-medium variance keeps a small bankroll alive longer than most, and the fact it sits at UKGC-licensed operators makes it a safe, regulated choice — which not every classic on our site can claim. It is for casual players, bingo-site regulars and anyone who values steady, low-stakes play over feature overload, not for variance-chasers. If you enjoy slots like Double Bubble, the natural next steps are other Gamesys classics such as Pirates Plunder and Battleship Wild Targets, or fruit-led slots like Berryburst.

What is the Bubble Line in Double Bubble?
The Bubble Line is a special highlighted line across the reels. When a winning combination lands on it, the payout is multiplied by up to 22x. It is the slot’s signature feature and the main source of its bigger wins, since standard line wins are fairly small.

What is the maximum win on Double Bubble?
The maximum win is 20,000x your stake. In practice the bigger payouts come from winning combinations landing on the Bubble Line with a high multiplier applied. It is a reasonable ceiling for a classic-style slot, though far below modern high-volatility games.
Who makes Double Bubble and is it UK-licensed?
Double Bubble was built by Gamesys, whose games studio is now branded Roxor Gaming. Gamesys was acquired by Bally’s Corporation in 2021, and in 2025 Bally’s agreed to sell its Gamesys interactive business to the Greek group Intralot. Throughout, the slot has remained available at UK Gambling Commission-licensed operators such as Jackpotjoy, Virgin Games and Double Bubble Bingo, so UK players are fully protected.
Is Double Bubble high or low volatility?
It sits at the low-to-medium end. You can expect fairly frequent small wins rather than long dry spells punctuated by huge payouts, which is a large part of why it remains popular with casual and bingo-site players. The trade-off is that genuinely big wins are rarer.
Can I play Double Bubble for free?
