Double Bubble Megaways Slot Review

Last Updated on August 10, 2026 by Maurya

Double Bubble Megaways takes one of Roxor Gaming’s most recognisable fruit-machine concepts and gives it a considerably more modern engine. Instead of relying on the traditional paylines associated with the original Double Bubble, this edition uses the Megaways mechanic to generate as many as 117,649 ways to win on a spin. It then adds Bubblemania, free spins, extra Wilds and a progressive jackpot to the familiar fruit-and-bubbles theme. Current operator listings continue to identify Roxor Gaming as the provider of Double Bubble Megaways.

First released on 29 March 2021, Double Bubble Megaways remains available at selected online casinos in 2026. The game uses six dynamic reels, carries an advertised RTP of 95.48%, and is generally classified as a high-volatility slot. Its theoretical stake range is commonly listed at 0.20 to 20 credits per spin, although the amount actually available to you will depend on the casino and gambling regulations in your jurisdiction.

The big question is whether adding Megaways improves Double Bubble or simply makes an old slot more complicated. In our view, the answer lies somewhere in the middle. Double Bubble Megaways is refreshingly uncomplicated compared with many modern Megaways releases, yet Bubblemania and the progressive jackpot provide enough personality to stop it feeling like another generic dynamic-reel game.

What Is Double Bubble Megaways?

Double Bubble Megaways is a modernised version of the Double Bubble concept that first appeared in 2006. The newer edition keeps much of the original visual identity but replaces the old fixed-reel approach with the licensed Megaways system developed by Big Time Gaming.

Megaways changes the number of symbols appearing on each reel from one spin to the next. This means the number of possible winning combinations constantly changes rather than remaining fixed.

Big Time Gaming describes Megaways as a dynamic reel-modifier system capable of producing up to 117,649 ways to win in its traditional six-reel configuration. Double Bubble Megaways applies that concept without loading the game with an excessive number of side features.

That simplicity is one of its strengths. Many newer Megaways slots combine cascades, multipliers, collection meters, bonus buys and several secondary modifiers. Double Bubble Megaways focuses primarily on variable reels, Bubblemania, Wilds, a free-spins round and the jackpot.

It is worth noting that this is not a conventional cascading Megaways slot. Specialist game documentation specifically notes that Double Bubble Megaways does not use the familiar cascading-wins system found in titles such as Bonanza. Instead, Bubblemania acts as its main way of enhancing qualifying base-game wins.

Double Bubble Megaways RTP and Volatility

Double Bubble Megaways has a published return to player of 95.48%. Specialist game data breaks this down as approximately 95.33% for the underlying game plus a 0.15% contribution toward the progressive jackpot.

RTP is a theoretical long-term mathematical percentage rather than an indication of what an individual player should expect during a particular session. A 95.48% RTP does not mean you will receive £95.48 for every £100 wagered. Actual short-term results can vary dramatically, particularly in a high-volatility game.

The 95.48% figure is also lower than the RTP found on some competing slots, so players who make RTP a priority may find more attractive alternatives elsewhere. SlotCatalog similarly characterises the figure as being on the lower side for the market.

Volatility is officially reported by specialist databases as high. That designation suits the game. The progressive jackpot and more substantial bonus potential are balanced by the possibility of uneven returns and quieter periods between stronger results.

For that reason, Double Bubble Megaways is more appropriate for players comfortable with fluctuating results than for somebody specifically searching for a low-volatility slot built around frequent small wins.

How the 117,649 Megaways System Works

Traditional slots typically use a fixed number of paylines. Double Bubble Megaways instead calculates winning ways according to the number of symbols visible across its six reels.

The reel heights change from spin to spin. Sources documenting the game describe the reels as capable of displaying multiple symbol positions and producing anywhere from several hundred combinations up to the headline 117,649 Megaways.

Winning combinations generally form across adjacent reels beginning from the left. Because reel height varies, a spin displaying a large number of symbols can offer significantly more possible combinations than a spin showing smaller reels.

However, “117,649 ways to win” should not be interpreted as 117,649 chances of making a profit. It describes the game’s combination structure. The outcome of every wager remains determined by the slot’s mathematics and random game result.

That distinction matters because large Megaways numbers can look more impressive than they really are. More active ways do not transform the game into something predictable, and they provide no strategy for guaranteeing a win.

Symbols and Paytable

Visually, Double Bubble Megaways stays close to its fruit-machine roots.

Players will encounter recognisable symbols including cherries, oranges, watermelons, bells and red sevens, along with lower-value playing-card icons. The pink Bubble Wild is one of the most important symbols because it can substitute for normal paying symbols to help complete combinations.

Current BetVictor documentation identifies the red seven as the highest-paying standard symbol in its displayed paytable, followed by the bell and watermelon. The exact game rules and prize information should nevertheless always be checked within the version offered by your casino before wagering.

The presentation itself deliberately avoids the cinematic style used by many newer online slots. Double Bubble Megaways looks more like a colourful retro fruit machine crossed with a bubble-making contraption.

That will divide opinion. Players who want elaborate 3D animation or narrative-driven slots may find it dated. Players who prefer uncluttered reels and familiar symbols may appreciate its simplicity.

Bubblemania Feature Explained

Bubblemania is the feature that gives Double Bubble Megaways its strongest individual identity.

Some regular symbols can land encased in bubbles. If a winning combination is formed entirely from these bubbly symbols, including qualifying Wilds, the Bubblemania machine activates. After the initial win has been calculated, the machine adds additional matching bubble symbols to the reels, potentially increasing the value of the existing combination.

It is a clever alternative to conventional cascading reels.

Rather than removing winning symbols and dropping replacements into their positions, Bubblemania concentrates on expanding a qualifying bubble-based win by pumping more matching symbols onto the screen.

The result is easy to understand visually. You do not have to follow a complicated meter, collect tokens or remember several multiplier rules. When the right type of win lands, the bubble machine comes to life and attempts to make that combination bigger.

For a slot built around a nostalgic theme, this is arguably the best design decision Roxor made. Bubblemania feels relevant to the Double Bubble branding rather than being a generic mechanic added simply because modern slots are expected to have multiple features.

Double Bubble Megaways Free Spins

The free-spins feature is triggered by landing three or more Scatter symbols on the reels. Once activated, players move to a bubble-selection stage that determines the number of free spins awarded.

The bonus round increases the importance of bubbly Wild symbols. Game documentation indicates that the Bubblemania machine becomes substantially more active during free spins, adding extra bubbly Wilds to the reels.

That gives the bonus a different rhythm from the base game without changing the core mechanics completely.

Scatters can also matter after the feature has begun. Landing at least two Scatters during a free spin can generate another bubble selection, creating an opportunity for additional spins or a shot at the progressive jackpot.

This makes retriggers particularly interesting because they are not simply a fixed number of extra spins. They reconnect the bonus to the bubble-popping selection mechanic and jackpot feature.

Progressive Jackpot

Double Bubble Megaways includes a progressive jackpot, which is one of the major differences between this title and many standard Megaways slots.

Multiple reputable reviews report a jackpot seed of around £25,000, with part of the slot’s RTP contributing toward the progressive prize. SlotCatalog specifies that approximately 0.15 percentage points of the game’s 95.48% RTP are allocated to the jackpot contribution.

The jackpot opportunity is connected to the free-spins bubble selection and can appear when triggering or retriggering the bonus.

Because progressive jackpots vary over time and may depend on the participating operator or network, the live jackpot figure displayed inside the casino should always be considered more authoritative than a static number quoted in a review.

It is also important not to confuse the progressive jackpot with the slot’s conventional maximum-win multiplier.

Published third-party sources currently disagree over the precise fixed maximum payout for Double Bubble Megaways. For example, SlotCatalog reports 5,000x, GMBLRS displays 12,500x in its database, while several other current slot directories list 1,000x.

Because of that inconsistency, we recommend checking the actual in-game paytable and rules at the casino where you play rather than relying on a fixed max-win number copied from a third-party review. That is the more accurate approach and avoids confusing a standard payout cap with progressive-jackpot potential.

Betting Range and UK Stake Limits

The original technical specification for Double Bubble Megaways lists stakes from 0.20 to 20 credits per spin.

That does not mean every player in every country will be allowed to stake that amount.

In Great Britain, statutory limits now cap online-slot stakes at £5 per game cycle for players aged 25 or over and £2 for players aged 18 to 24. The Gambling Commission confirms that the £5 limit took effect on 9 April 2025 and the additional £2 limit for 18–24-year-olds followed on 21 May 2025.

Consequently, a UK-licensed version of Double Bubble Megaways cannot simply offer the old £20 maximum stake to British customers.

This is an important detail when reading older slot reviews, many of which still quote the original theoretical £20 maximum without accounting for newer gambling legislation.

Double Bubble Megaways on Mobile

Double Bubble Megaways supports mobile play as well as desktop and tablet devices. Specialist game records identify a mobile version, while recent reviews describe the game as HTML5-compatible and designed to adapt to smaller screens.

The uncomplicated interface lends itself well to mobile screens. Six dynamic reels can become visually busy when fully expanded, but the absence of multiple side meters and complicated control panels keeps the important information relatively easy to follow.

Players should expect the same fundamental mechanics on supported mobile browsers: changing Megaways, Bubblemania, Wilds, Scatters, free spins and the jackpot opportunity.

Can You Play Double Bubble Megaways for Free?

Demo availability depends heavily on the market and website you are using.

Some international slot-information websites display free-play versions, but licensed operators may apply different access rules or require an account. Recent UK-focused reviews report that a conventional unrestricted demo is not offered to British players at some participating operators.

The safest approach is therefore to check the casino or game provider available in your jurisdiction rather than assuming a free version will exist.

A demo, where legally and technically available, can be useful for understanding the reel layout and features, but it does not change the mathematics of the real-money game or provide a method for predicting future outcomes.

Autoplay, Turbo Spins and UK Rules

Older technical databases may still show Autoplay as a feature because Double Bubble Megaways was originally released before several major UK safer-gambling reforms.

At licensed British operators, however, online slots cannot provide conventional Autoplay. The UK Gambling Commission introduced its prohibition on Autoplay for online slots from 31 October 2021, requiring customers to initiate each game cycle individually.

British slot games must also maintain a minimum 2.5-second game cycle, and features intended to accelerate results are restricted.

Therefore, differences between screenshots in older reviews and the game you see at a regulated UK casino do not necessarily mean anything is wrong. They may simply reflect regulatory changes implemented after the slot originally launched.

Double Bubble Megaways Pros and Cons

Is Double Bubble Megaways Worth Playing?

Double Bubble Megaways works best when judged as a simple Megaways slot with a distinctive jackpot feature, rather than as a cutting-edge showcase of everything the Megaways engine can do.

The dynamic reels make the original Double Bubble formula substantially more varied, while Bubblemania gives the game an identifiable feature of its own. Up to 117,649 winning ways provide the large reel configurations Megaways players expect, and the free-spins round makes good use of additional bubbly Wilds.

The progressive jackpot is another meaningful selling point.

There are compromises, however. An RTP of 95.48% is unlikely to impress players who actively compare return percentages, and high volatility means this is not designed to deliver an especially smooth sequence of results.

The absence of cascading wins is also unusual for a Megaways game. Some players will appreciate the simpler format; others may feel that the experience lacks the escalating chain reactions associated with famous Megaways slots.

Visually, Double Bubble Megaways also makes little attempt to disguise its heritage. It remains bright, bubbly, fruity and deliberately old-school.

For fans of the original Double Bubble series, that is probably an advantage.

Responsible Gambling: What Players Should Know

No slot strategy can change the programmed RTP, volatility or random outcome of an individual spin. Megaways counts, bonus features and previous results do not predict what will happen on the next wager.

Players using real money should decide on an affordable spending limit before starting, avoid increasing stakes in an attempt to recover losses and view slots as paid entertainment rather than a way of generating income.

If you are playing in Great Britain, use a casino licensed by the Gambling Commission and make use of available safer-gambling controls such as deposit limits, time-outs and self-exclusion where appropriate. The Gambling Commission regulates businesses offering gambling services to consumers in Great Britain and provides information on checking whether an operator is licensed.

Final Verdict

Double Bubble Megaways earns its place in the series by modernising the original formula without losing its personality.

Its six dynamic reels and maximum 117,649 Megaways give it the scale expected from the format, while Bubblemania provides a refreshingly straightforward alternative to the cascades and multiplying reaction systems found in many competing titles.

Free spins are worthwhile because the Bubblemania machine becomes more influential, while the progressive jackpot gives every bonus trigger an additional layer of interest. At the same time, the 95.48% RTP and high volatility are important drawbacks that should not be overlooked.

Our assessment is that Double Bubble Megaways is best suited to players who enjoy classic fruit-machine visuals but want something more varied than a traditional fixed-payline slot. It is also an interesting choice for Megaways fans who prefer relatively easy-to-understand features instead of bonus rounds containing several overlapping modifiers.

Players searching for high RTP, sophisticated graphics or the cascading-win mechanics normally associated with Megaways may prefer other games.

Overall rating: 8/10
