Double Bubble from Gamesys is so old school it’s brand new, with 5 reels, 20 paylines and a possible x20,000 top win. The reels are full of classic fruit machine symbols - bells, grapes, plums and melons.

First impressions of Double Bubble online slot

The overall scene of Double Bubble is faintly reminiscent of an old-fashioned washday, with a bit of American diner thrown into the mix. The setting for the reels is a pink console screen, which is set on a pink and white surface, giving a rough three-dimensional effect, which is more like playing on a traditional land-based machine.

Double Bubble Slot

Double Bubble symbols and paytable

We’ve already taken a look at the highest-paying symbol on the paytable, which is the Wild. This is one of the symbols that pay out cash prizes for spinning up even two examples on an active payline.

The first instance of a winning symbol must always appear on reel 1, with subsequent matches at least on reel 2, in accordance with payline structures.

Spin up two Wilds and you’ll win back 20x your line bet. And those of you of a mathematical persuasion will instantly see that this would cover the cost of your stake if you were playing with all 20 paylines active.

Top Wins

Remember, prizes are based on a per-line basis, not on the total amount of your bet. And of course, the rewards are better, the more Wilds you spin up with a single spin.

Three matches will pay out 100x your line bet, increasing to 500x for four matches, and the top cash payout of 20,000x the player’s line bet for five of a kind on a payline.

The other symbols on the reels aren’t nearly so generous, but the other three top-paying icons still pay out some decent cash prizes. Lucky Number 7 lives up to its name with a top cash payout of 500x your line bet.

2 of a Kind Wins

Cash prizes worth 200x and 50x the line bet are paid out for spinning up four and three of a kind respectively, but the payout for spinning up two matches, although still welcome, isn’t going to have an impact on the player’s overall returns.

Liberty Bell

The same is true of the next two symbols, the golden Liberty Bell and the green triple Bar. Both of these payout just 2x your line bet for two matches, rising to a much more respectable 25x for spinning up three of a kind.

Four matches will award you 100x for the triple Bar, and 200x for the Liberty Bell, with both symbols paying out 500x the line bet for five of a kind across an active payline.

Bar Symbols

The blue double and pink single bar symbols both return 20x the line bet for matching up three of a kind on a payline. This increases to 50x for four matches and 500x for spinning up matching examples of either symbol.

Next come the plum and orange symbols, both of which offer rewards of 10x, 20x and 200x for landing three, four or five of a kind, respectively.

The Fruit Symbols

Grapes, watermelons and cherries won’t return your stake, even for spinning up three matches across a payline, paying out just 5x your line bet. This increases to 20x for four matches, winning back your stake if you included all 20 paylines, and rises even further, to 100x for five matches.

How to Play Double Bubble Slots

A few quick steps to get you started:

  1. Once the game is loaded, click on the "..." button in the top right and read the paytable, RTP and Rules info.
  2. Within the "..." menus you can also choose your sound settings
  3. Choose your coin size using the - & + buttons.
  4. 20 paylines are adjustable so select your paylines using the - & + buttons (you'll need to play 20 lines to get the x22 Bubble line)
  5. When you are happy with your total bet, set a session budget, hit SPIN and enjoy your session responsibly.

You're also able to choose a coin size between 0.01 and 5. Whatever you choose, it will be multiplied by the number of paylines that you're wagering on to calculate your total wager.

There is no autoplay option, unfortunately. To hit winning combinations, you must land 3 or more symbols on the same payline.

What sets Double Bubble apart from other similar slots is that some of the symbols actual payout of 2-of-a-kind winning combinations, increasing the overall volatility of the game and helping you trigger winning combinations more frequently. To trigger the bonus round, you need to land the bonus symbols anywhere on the wheels.

Double Bubble Volatility and RTP

Double Bubble has a classification of medium/high volatility.

The Return to Player on Double Bubble is 96.02% - this means that, in theory, if you were to wager 100 you would get paid out 96.02 - of course, you can't bank on this as the calculation is done over an infinite number of spins and the smaller your wager the higher the variation will be.

Proceed with caution

Players, particularly newbies, can quickly get caught out playing medium- or high-volatility games that don’t offer an automatic increase on your balance with every win.

It’s all too easy to see the wins appearing, and hearing the cheery trumpeting that accompanies every winning spin, and assume that your balance is increasing. But even with several wins under your belt, that balance could be quickly dwindling away, so keep a close watch on your progress.

How to Win at Double Bubble

  • The wild in Double Bubble could not stand out more - it comes in the form of the game’s own pink logo!
  • The wild substitutes for all the other symbols except the Double Bubble bonus icon.
  • The Bubble Popper bonus is triggered whenever the bonus symbol shows on reels one, three and five. Players are then presented with a bonus screen where they can take their pick from a selection of bubbles, each one containing a different bonus multiplier.
  • The Bubble Line wins are awarded from the base paytable and multiplied by the Bubble Line multiplier. Only the highest win is paid on the Bubble Line. The Bubble Line multiplier is equal to the number of coins bet, with the exception of when 20 coins are bet; in this case, the multiplier is increased to x 22.

Double Bubble Features Explained

There are two bonus games that can occur on the reels of Double Bubble. The first is the Bubble Pop Bonus, and the other is the Bubble Line Bonus.

Spin up three Scatters and the screen changes, showing you three floating bubbles. Choose one to pop, and it will burst, leaving you with an instant Multiplier win, applied to your bet.

The Bubble Line Bonus is constantly being played out, just underneath the reels. You’ll see the word BONUS spelt out in bubbles towards the bottom right-hand side of the playing area. Every time a symbol lands on the reels encased in a bubble, it is collected in one of the Bonus Bubble positions.

Bonus Pays

These symbols then operate according to normal paylines, so if you spin up any combination that would achieve a win on the main reels, it will be awarded for the Bubble Bonus payline too. But this extra payline won’t just pay out the usual winning amounts.

The winning sum is subject to a multiplier equal to the number of paylines included with the winning spin. And if you opted to include all 20 paylines, a Multiplier worth 22x the stake is applied, which could lead to some huge cash prizes!

Double Bubble - The 100 Spin Experience

With our 100 Spin Experience, we'll take an in-depth look at the gameplay of this popular online slot to let you know exactly what it's like to give it a spin.

The first thing to note is how quickly the game loads. It was a matter of seconds before we were able to give the game a spin and could get started right away, which is always a plus when you're playing on the go.

Unfortunately, there was no autoplay feature, so we had to hit the spin button on every round - which is a bit of an inconvenience if you want to multitask.

Hard to hit Bubble Line

Our main gripe about the game is that the Bubble Line bonus is a bit difficult to grasp. It was only after a few rounds that we understood that you have to land a symbol on the bubble line and have that symbol land on a paying line.

Aside from that, Double Bubble is a great online slot that is sure to keep you entertained and engaged as you spin the reels. You'll be thrilled with the frequency of the payouts and the Bubble Line bonus does add to the excitement - once you figure out exactly how it works!
