Double Bubble vs Fluffy Favourites compares two slots that grew up on UK bingo sites. Gamesys's Double Bubble has the higher RTP (96.02%) and medium volatility; Eyecon's Fluffy Favourites is high volatility at 95.39% (with a 93.29% version also in circulation) and a 5,000x ceiling built on tripled free spins.
Double Bubble's 96.02% RTP beats Fluffy Favourites' top 95.39%, and by much more if a casino runs Fluffy's 93.29% version.
Double Bubble is medium volatility; Fluffy Favourites is high, so its sessions swing harder.
Fluffy Favourites' free games triple every win and the pink elephant wild doubles the wins it completes.
Fluffy Favourites has a 5,000x max win; Double Bubble's ceiling varies by version, so we don't state one.

Double Bubble vs Fluffy Favourites in brief
Both games became familiar to British players through bingo-and-slots sites rather than big casino brands, and both are five-reel, three-row video slots with bright, light-hearted themes. That's where the likeness ends. Double Bubble is the steadier of the two on paper, with medium volatility and a higher return. Fluffy Favourites trades a lower RTP for a high-volatility bonus where wins are tripled. This page belongs to our wider set of slot comparisons.

Toybox Pick and Free Games
Two cells say 'varies' on purpose. Double Bubble has been released in more than one edition, and the features and top prize differ between them, so a single figure would mislead. We'd rather point you to the help screen of the version in front of you.
Two bingo-site slot machines with different roots
Gamesys built Double Bubble in-house for its own bingo and casino brands, which is why it was for years a game players met alongside bingo rooms rather than in every casino lobby. Its bubbly theme and simple layout suited quick sessions between bingo games.
Fluffy Favourites comes from Eyecon, a studio founded in Australia in 1997 as a computer game company that opened a European hub in Guernsey in 2015 and has been owned by Playtech since 2017. Its fairground-toy theme is light, but the game itself is for adults only, like every real-money slot. The cartoon look led to a sequel, Fluffy Too, compared in detail in Fluffy Favourites vs Fluffy Too.
How Fluffy Favourites works: elephant wilds, claw picks and tripled spins
The pink elephant wild
The pink elephant is both wild and scatter. As a wild it substitutes for paying symbols and doubles any win it completes, a classic wild multiplier. As a scatter, three, four or five anywhere start the Free Games with 15, 20 or 25 spins.
Toybox Pick
Three, four or five claw scatters in the base game trigger the Toybox Pick, giving three, four or five picks. Each pick reveals a cash prize, a format our pick-me bonus page explains in general terms.
Free Games at 3x
In the Free Games every win is multiplied by three, and three or more elephants retrigger the round; the help screen sets a maximum of 400 spins in total. The two multipliers stack. Worked example at 25p a spin on 25 lines (1p a line): a line win normally worth 40p, completed by one elephant wild, pays 80p in the base game and £2.40 in the Free Games (40p × 2 × 3).
How Double Bubble works, and why the version matters
Double Bubble plays as a 20-line, five-reel game with a wild symbol, line wins from left to right and bonus features triggered by special symbols. Beyond that, the details depend on the edition your casino runs, because Gamesys has released several. Rather than describe features that may not match your screen, here is how to read the version in front of you.
Open the game and tap the 'i' or menu icon before you stake anything.
Read the paytable page for the wild: note whether it multiplies wins and on which reels it lands.
Find the bonus rules: note the trigger symbols, how many are needed and what the round awards.
Look for any jackpot section: a jackpot edition takes part of each stake for the jackpot pool.
Note the RTP line and compare it with the 96.02% top figure.
Jackpot editions usually report the return in two parts, the base game and the jackpot contribution; our page on how jackpots are funded explains why.
RTP: Double Bubble vs Fluffy Favourites, and the 93.29% question
At top settings the gap between the two games is 0.63 percentage points. The bigger question is which Fluffy Favourites version your casino runs: at 93.29%, the theoretical house edge almost doubles compared with Double Bubble. The table shows the average cost of 100 spins at each setting.

At £1 a spin, 100 spins cost £3.98 on average on Double Bubble, £4.61 on Fluffy Favourites at its top setting and £6.71 at the lower one. The Gambling Commission's rules on game information (opens in a new tab) mean the return should be shown in the game's information, and our guide to reading slot RTP in the UK shows where to look. RTP variants explains why one game can have several settings.
Medium vs high volatility: how each slot spends a £10 budget
Take £10 at 10p a spin: 100 spins if nothing came back. On a medium-volatility game like Double Bubble, regular small returns usually stretch that into more spins. On a high-volatility game like Fluffy Favourites, it's more common for £10 to run out before the Free Games appear, and also possible for one round with tripled wins to return several times the budget. Neither result is predictable, which is the point of volatility.
Max win at UK stake limits
In Great Britain, online slot stakes are capped at £5 per spin for players aged 25 and over and £2 for 18 to 24-year-olds, as the Commission's stake limit guidance (opens in a new tab) sets out. Fluffy Favourites' 5,000x ceiling converts like this.

The 5,000x top prize on Fluffy Favourites needs a screen full of top-paying symbols, which is extremely rare and more likely in the Free Games thanks to the 3x multiplier. Double Bubble's top prize depends on the edition, especially if a jackpot is attached.
Lines and stakes on each slot machine
Fluffy Favourites lets you play from 1 to 25 lines. Fewer lines reduce the total stake, but they also reduce the number of ways a spin can win, so a 5-line spin is not a cheaper version of the same game. Our answer to should you play max lines? explains the trade-off, and the line bet entry shows how line bet and total bet relate. Double Bubble's 20 lines are played together in the editions we know of; check the stake panel.
Low stakes are a big part of both games' appeal. Our guide to penny slot machines explains how small line bets still add up: 100 spins at 25p is £25 staked.
UK rules for Double Bubble and Fluffy Favourites
No autoplay, no turbo and at least 2.5 seconds per spin on UK versions since 31 October 2021 (see the slot game design rules).
Stakes capped at £5 (25+) or £2 (18–24) per spin.
Wins equal to or less than the stake aren't celebrated with win animations; see losses disguised as wins.
Demo play is free only after age verification.
Bonus wagering on any welcome offer is capped at 10x since 19 January 2026.
These rules apply to bingo-site slots exactly as they do to casino lobbies, because they attach to the operator's licence, not to the type of site.
Myths about bingo-site slots
'Bingo-site slots pay more because the site wants you back for bingo.' The RTP is set by the game version, not the site's other products.
'The claw is a skill game.' The Toybox Pick prizes are decided by the game's random number generator, not by timing.
'Playing fewer lines keeps the RTP the same and saves money.' It lowers the stake, but you lose the wins those lines would have paid.

Frequently asked questions
Which has the better RTP, Double Bubble or Fluffy Favourites?
Double Bubble has the better top RTP at 96.02%, compared with 95.39% for Fluffy Favourites. A 93.29% version of Fluffy Favourites also exists, which would make it noticeably more expensive over time: about £6.71 per £100 staked on average, against £3.98 on Double Bubble. Always check the figure in the game's help screen before playing. Our RTP explainer covers what the number does and doesn't mean.
Is Fluffy Favourites high volatility?
Yes, Fluffy Favourites is rated high volatility, while Double Bubble is medium. That means Fluffy's results swing more: long runs with little coming back are normal, and much of its value sits in the Free Games, where wins are tripled. A small budget can run out before the bonus appears. See volatility and our guide to slot volatility and budgets for planning a session.
How do you trigger free spins on Fluffy Favourites?
Land three, four or five pink elephant scatters anywhere to win 15, 20 or 25 free spins. All wins in the round are multiplied by three, and three or more elephants during the round retrigger it, up to a maximum of 400 spins in total. The elephant also acts as a wild that doubles wins, so a win completed by an elephant in free spins is multiplied six times. Our Fluffy Favourites slot page has the full breakdown.
What is the Toybox Pick on Fluffy Favourites?
The Toybox Pick is a pick-style bonus triggered by three, four or five claw scatters in the base game, giving three, four or five picks. Each pick reveals a cash prize, and the total is added to your balance. The outcome is decided by the game's random number generator, so there's no skill in choosing. It's separate from the Free Games, giving the slot a second feature route. See pick-me bonus for how these rounds work.
What is the max win on Fluffy Favourites?
Fluffy Favourites' max win is 5,000x the stake. On a £5 spin, the most a player aged 25 or over can stake, that is £25,000; at the £2 limit for 18 to 24-year-olds it's £10,000; at 25p it's £1,250. Reaching it needs a full screen of the top symbol, which is very rare. Double Bubble's ceiling varies by edition, so check its help screen. Our max win caps page explains how these figures are set.
Why does Double Bubble have different versions?
Gamesys released Double Bubble in more than one edition over the years, including versions with a jackpot attached, and features, top prizes and RTP can differ between them. That is why our data records the max win as varying by version. The help screen of the game in your casino lobby is the reliable source for the rules you're actually playing. Our Double Bubble slot page and the slot sequels guide explain more.
How much does 100 spins cost on Double Bubble and Fluffy Favourites?
At 25p a spin you stake £25 over 100 spins. At top RTP the average theoretical cost is about £1.00 on Double Bubble and £1.15 on Fluffy Favourites, or £1.68 on Fluffy's 93.29% version. At £1 a spin those become £3.98, £4.61 and £6.71. Real sessions vary a lot, especially on high-volatility Fluffy. Use our slot cost calculator to test your own stake.
Can I play Fluffy Favourites with fewer lines?
Yes, Fluffy Favourites lets you choose between 1 and 25 lines, which lowers your total stake per spin. The catch is that fewer lines means fewer ways to land a win, so you're not playing a cheaper copy of the same game. Scatters still pay anywhere. Many players keep all 25 lines and lower the line bet instead. Our answer to should you play max lines? walks through the maths.
Are Double Bubble and Fluffy Favourites available in demo mode?
Many UK casinos and bingo sites offer free demo play of both games, after age verification. The verification rule has applied since May 2019 and covers every free-to-play version at a licensed operator. Because the demo runs the same rules as the paid game, you can watch how the Free Games or bonus rounds behave without staking money. Our demo slots guide explains what a demo can and can't tell you.
Are bingo-site slots safer than casino slots?
No, a slot on a bingo site carries the same house edge and risks as one in a casino lobby. The same Gambling Commission rules apply: stake limits, no autoplay, 2.5-second spins and age verification. Treat it as paid entertainment, set a deposit limit and take breaks. If play starts to feel out of control, our help for slot players page lists free support, including the National Gambling Helpline on 0808 8020 133.
