About Double Bubble Slot Game
The design doesn’t draw from a single inspiration, mixing plenty of fruity colours and pastel shades together into something that’s really each on the eyes! With twenty paylines and fifteen spaces split across five reels, there’s a lot that can happen in every single spin. You can find this game at some of the best online slot sites.
The symbols follow suit, mixing creative bonus images with lovingly-rendered versions of your classic slot fruits and berries. The bonus symbols are just as bubbly as you’d expect: bubbles for Bonus symbols and soapy-looking gems for BAR symbols.
The elusive Double Bubble acts as your Wild, and the Lucky Number 7 earns you big payouts if you can match at least two.
How To Play Double Bubble Online
- Use the + and – buttons at the bottom of the screen to choose your coin size and overall stake.
- Select the number of paylines you want to play with. These can be selected with the numbers at the sides of the screen.
- You can also use BET ONE to add a single payline or BET MAX to select them all.
- Once you’re ready to play, click the green SPIN button at the bottom right of the screen.
The game’s most unique feature is the Bubble Line. Special icons that appear during a spin will be added to this Bubble Line, giving you the opportunity to combine five of them into a free x100 wager multiplier if you get five matching symbols. Getting four fruit symbols will boost your wager up to x20 instead.
The Wild symbols give you an even bigger bonus of x20,000 if you can match five of them, and two Wild symbols will give you an x20 bonus.
The Bubble bonus symbol acts as a scatter, triggering the Bubble Pop bonus round if you get one on the first, third and fifth reels. This bonus round lets you select one of three hidden multiplier bonuses for the wager that triggered it.
Players can activate the Auto Spin feature if they want to perform multiple spins in quick succession.
What Symbol Triggers Double Bubble Bonus Free Spins?
Surprisingly, there isn’t an easy way to earn free spins through playing. Free spins are generally relegated to site bonuses or first deposit features, and none of the spaces will add free spins to your account or session.
Paylines and Stakes
The game has 20 paylines that can be selected in order, as well as coin size: 1p, 2p, 5p and 10p. The amount of paylines used and the related coin values change the overall stake. These paylines are numbered at the side of the slot screen, and can’t be activated out of order.
Double Bubble Slot Game Software
The Double Bubble game is powered by GameSys’ software.
Established in 2001, GameSys have been named as one of the fastest-growing technology companies in the UK and own large brands such as Virgin Games and Woman’s Own Bingo. The company has also earned various industry awards and accolades, including being voted Best Online Bingo Software of 2015 by WhichBingo.
GameSys are also known for their game variety, including both paid and free bingo game types as well as an extensive list of slot games: this includes similar games like Doubly Bubbly. Many of them include gimmicks specific to each game, such as the Bubble Line in this example.
What is the Double Bubble RTP?
The current RTP (Return to Player) of Double Bubble is around 96% across all sites.
GameSys have set this RTP for every version of the game, so playing the game on another site won’t make these odds any better or worse. This Return to Player average doesn’t take promotions, such as 30 free spins on a first deposit, into account.
The game has quite a volatile set of odds, since this is a high-variance game. There isn’t any built-in free spins and the Return to Player can easily be modified by the game Double Bubble bonus features.
This means that payouts are less regular and there can be higher risk when you play with larger stakes, but you’re also more likely to earn big bonuses.
This stands out among many other slot games for being volatile and packed full of bonuses other than free spins. While GameSys often give out free bingo first deposit bonuses and similar extras, the lack of bonus spins feeds into the gameplay here: wagers are high-risk but higher-reward.
While free spins could be an area to improve on with Double Bubble considering how well GameSys handle first deposit and free bingo bonuses in other games, everything about how you play is excellently designed.
GameSys operate a lot of sites, from Virgin Games to Womans’ Own Bingo, so there are other places you can play games like this to get free bingo and slot bonuses. Although this isn’t one of those games, the bonuses are much more direct and impact than a free bingo ticket or slot spin it’s still an enjoyable experience for almost any player!
