The Double Bubble slot machine payouts.
If you’re familiar with the Gamesys video slot games you’ve probably already noticed that the payout of the games is sometimes not disclosed. Jackpotjoy has now made it public that expected RTP of Double Bubble slot is 96% when playing all 20 winlines and 92.5% if you play between 1 and 19 pay-lines.
My session with Double Bubble slot lasted around 30 minutes during which I placed a total of 203 spins with three different wager amounts. First I played a total of 150 spins with a £1 coin playing all 20 paylines, so stakes of £20 per spin. Then I switched to a £0.05 coin on all 20 win-lines and played 3 spins for a total of £1 per spin. And lastly, I played a total of 50 spins with a £4 coin on all 20 winning lines for a total of £80 per spin.
Out of the total 203 spins played on Double Bubble slots there were a total of 88 winnings spins across the three different wagered amounts. To be more specific, the game paid out a total of 55 spins @ £20 per spin, 2 spins @ £1 per spin and lastly 31 spins @ £80 per spin.
How much can you win in the Bubble Bonus game (Pick-a-box).
In Double Bubble slots game there’s a chance to increase your earnings on every spin thanks to the Bubble Pop Bonus game.
What’s the Bubble Pop Bonus you ask? The Bubble Pop Bonus is a ‘Pick ’emp’ style of bonus game which is triggered when the scatter symbol (the Bonus Bubble) shows on reels 1, 3 and 5.
Once the Bubble Pop Bonus game is activated, you will be taken to the bonus game screen which offers you three bubbles to choose from each of which hide a bonus amount.
You must choose one of these three bonus bubbles to reveal the bonus amount hidden within. When the multiplier is revealed, you bonus amount is multiplied by the bet position of the original spin which trigger the bonus game.
Once the Bubble Pop Bonus game is finished, you will return to the usual Double Bubble slot game to continue to play and all the winnings earned during this bonus game are added to your total balance.
Some of the complaints I’ve read about Double Bubble slots on other websites and forums is the lack of free spins and bonus games. While it’s true that there are no Free Spins on Double Bubble there is, however, one Pick ’em style bonus in this game.
Unlike other games like Houdini Slot, Greedy Goblins slots or Reel Deal Diner slot where the bonus game is engaging and a bit more entertaining, the bonus game at Double Bubble slot is somewhat straight-forward. Once you trigger the bonus, you’ll be presented with three Bonus Bubbles. Simply pick one of these three to reveal your prize and the bonus will end taking you back to the Double Bubble game.
In other games like Thunderstruck 2 slot the bonus game is where the money is and I’ve seen some complains about Double Bubble’s bonus game not being too generous. The truth is that yes, you won’t be winning millions from this bonus game but you won’t be leaving empty-handed either.
The amount you uncover by clicking one of the three bonus balls will be multiplied by 4 which in turn should produce some decent winnings. In my case I got 180 credits in the bonus ball which turned into a total winning of 720 credits (180 x 4). I don’t know about you but 720 credits won on a bonus game seems pretty generous to me and it’s probably about average when compared to most other video slot games worth your time and pounds.
How can you win in the In-line bonus game?
You can win up to 22 times your stake when you trigger the In-Line bonus game available in the Double Bubble slot game. If you look closely at the slot screen, you will notice there’s an area right below the reels (see image above); this is known as the Bubble Line and based on my own experience, this bonus game is where you can expect most of your highest earnings to come from. In Double Bubble slot, the Bubble Line Bonus is where the money is!
If you’re familiar with the traditional fruit-machines found at pubs around the United Kingdom, you will immediately recognize this style of bonus game. The way this Bubble Line bonus works is that every time you spin the reels, you have a chance to build an additional winning line on this bubble line apart from the winning combinations from the 5×3 reels layout of the game. Whenever you get two, three or more symbols of the same kind on this bubble line AND these symbols also appear on the top reels of the game, you will earn an additional bonus. The bonus amount will depend on the symbol you line up on this bubble line, the amount of matching symbols you get (min 2 or 3 depending on the symbol) and the amount of paylines that you are playing.
I’ve seen some players get confused with how this bonus works, so I’ll explain it using the example from the image on the left. In this specific case you can see that I got three (green) Bar symbols on the Bubble Line and because I matched these three Bar symbols with three Bar symbols on reels 1, 4 and 5, I activated the bonus. The amount won on the bonus was 2,200 and I will tell you where this comes from. If you look at the paytable you will see that getting three (green) Bar symbols pays out 100 credits and the bonus rules states that if you’re playing all 20 winlines, then your bonus is multiplied by 22. So, 100 credits for getting three Bars times 22 multiplier = 2,200 credits bonus. Pretty neat, isn’t?
The Bubble Line Bonus of Double Bubble slot is one the features of this fantastic video slot game which I have seen has caused the most confusion among some video slot players.
The Bubble Line Bonus works in a very similar way as the bonus featured on the traditional pub fruit machines found across the UK. If you’re not from the UK or you’re not familiar with these type of bonus I’ll explain it here.
As you see in the image, right below the five reels of Double Bubble slot, there’s one horizontal line with five slots. Every time you spin the reels, the game’s symbols spin from top to bottom on each of the five reels until the reels stop and each reels has it’s own symbols lined up. This is where you build your winning lines and payouts are calculated based on the paytable.
On top of the usual slot game (above), you will see that with each spin, there will be symbols showing up on these Bubble Line bonus slots. If you match the symbols from this line with the symbols showing on the reels above, then you will win an additional bonus. The payout of this bonus is based on the number of the matching symbols as per the paytable.
For example in the image you see that I got three (green) Bar symbols on the Bubble Line Bonus and I also got a (matching) Bar symbol on reels 1, 3, 4 and 5 on the Double Bubble slot game. The total bonus amount for matching these three symbols was 2,200. To work out this bonus amount we need to look at the paytable from where we know that getting three Bar (green) symbol pays out 100 credits. We were wagering on all 20 paylines which means the Bubble Line bonus will use a 22 multiplier. So three Bar symbols = 100 credits times 22 = 2,200 credits. And you don’t even need at winning payline for that bonus to be paid out!
Apart from the frequent and generous payouts of Double Bubble slot, this Bubble Line bonus is one feature that makes this game a killer game. Yes there are no free spins, expanding or sticky wilds and the Bubble Pop Bonus isn’t a millionaire maker on its own but with a feature like Bubble Line and amazing payouts you truly don’t need them. Grab your self a bonus and play online now – you’ll love it!
Does Double Bubble have a Wild Symbol? How much does it pay?
This Double Bubble slot review found that the wild symbol, represented by the Double Bubble image, as with most Wilds in online video slot games, the wild symbol can substitute any symbol to complete a winning payline except for the Bonus symbol.
Cash prizes that come from winning paylines using the wild symbol are awarded to only one single winning combination per spin. This means that when the Double Bubble wild symbol is used to complete more than one winning payline, the player will cash the prize of the highest value.
Luckily the Wild symbol in Double Bubble slots game seems to show up with an amazing frequency thus helping you create more and more winning combinations. In my experience with the game, the Wild symbol was truly my best friend and alley. As you can see in the image to the right, the Wild symbol can be crucial to complete that winning payline that truly boost your bankroll. In this specific case, the Wild simple helped me build a Five-of-a-Kind winning line using the Super 7 symbol which produced a massive 2,000 credits win.
How much do the symbols payout in Double Bubble slot?
Before diving into the most frequent and rewarding symbols of Double Bubble slot I just want to clarify again that this is only based on one single gaming session and you should not expect to ge the same results once you’re playing the game.
In my last experience playing Double Bubble I found the Watermelon and green Bar symbols (Bar, Bar, Bar) to be the most common symbols in a winning line which made up 15 and 13 of the winning lines respectively. These two are closely followed by the Grapes (note: plural!), Bells and Cherries symbols which produced 12, 11 and 10 winnings lines each, as shown in the table below.
Wild symbols are a fundamental part of any video slot game and this exercise goes to show how important Wild symbols are in creating winning lines playing Double Bubble slot. Since the Wild symbol substitutes for all symbols except Scatters (the bonus symbol), it´s no surprise that the frequency with which the Wild symbol appeared on a win line is related to the frequency with which each winning symbol shows up on the reels.
- Watermelon + Wild 5
- Bar Pink + Wild 5
- Orange + Wild 4
- Bells + Wild 5
- Cherries + Wild 3
- Grapes + Wild 4
- Bars Green + Wild 4
- Grape + Wild 2
- Super 7s + Wild 4
- Bar Blue + Wild 1

Learning the basics of game.
Today we have a How to Play Double Bubble Slots Guide prepared for you where we’ll run through the basics of playing this fantastic video slot game from Gamesys on any of the available bingo and casino sites.
Before we begin it’s worth noticing that this is a how to play guide for the truly beginners or those not familiar with Double Bubble slots at all. If you’re a more experienced slot player, I suggest that you check out our Double Bubble Slot Review here where you can find comprehensive information on this popular game.
If, on the other hand, you’re after the nitty-gritty of the game, you’d probably be interested in reading our geeky review on Double Bubble Slot Payouts and Bonuses here. That being said, let us get started with our How To Play Guide on Double Bubble Slots
How many paylines can you bet on Double Bubble?
The fact that Double Bubble slots machine is a multiline game does not mean you’re forced to wager on all 20 paylines every time, but doing so if highly recommended because of the reasons highlighted above.
You will notice there are three buttons on the bottom right corner of the game’s layout. To choose the number of paylines you want to activate, you can click the ‘Bet One’ button. Every time you click this button you will activate an additional winline starting with 1 payline and up to a maximum of 20 winlines. Once you have activated the number of winlines you want, just click the green ‘Spin’ button and let the reels do the rest.
If you want to play with the highest chance of winning then you will wager on all 20 paylines, and the fastest way to do this is to simply click the ‘Bet Max’ button and let the magic happen. Again, keep in mind that activating more winlines increases your odds of building a winning combination but it will NOT increase the payouts because these are determined by your coin size.
How is Double Bubble slots a Multi-line video slot?
What’s a multi-line video slot game, you ask? Multiline slot machines are games where you can place wagers (bets) on more than one win line at the same time, or in the same spin.
Why bet on more than one winline? Simple, to have more chances of winning! The point of offering more than just one winning line on a slot machine game is to give players more chances of winning a cash prize on each spin. If you had just one line that means you only have one single chance of winning on every spin, whereas if you bet (activate) on more than one winline, there will be multiple winning combinations and therefore more chances of winning on each spin.
What are the min and max coin sizes available in Double Bubble?
You should note that betting on more than one payline will increase your overall stake size (total bet per spin) because your coin size is multiplied by the number of active paylines. For example if you choose a 10p coin size to play Double Bubble slot and you activate all the 20 winlines the game offers, you’re total stake/bet per spin will be £2. You will adjust your coin size depending on your bankroll size, your style of play and how much of a risk taker you are.
The coin sizes available in Double Bubble slots range from just 1p and up to £4 for the real High Rollers and professional slot players. Learning how to choose your coin size is essential because this is how you take control over the amount of money you bet on every spin. The coin size is also very important because the payouts on the game will be multiplied by the coin size, so the higher the coin size, the higher the payout!
Does Double Bubble have an Autospin feature?
Yes, you will notice that in Double Bubble slots game (and many other slot machines) there’s an ‘Auto Spin’ button. This feature gives you the opportunity to choose how many spins you would like to play with the current set up of coin size and paylines and have the game play them out for you without having to click ‘Spin’ every time.
Using the Auto Spin feature may seem unnecessary at first and for some players but it’s quite handy if you’re having longer gaming sessions. You should note that the Auto Spin will stop when a bonus game is triggered and hand over the controls back to you to play out the bonus feature. There is also a ‘Stop’ button during the Auto Spin to cancel the feature; thus making sure you’re in control of the game all the time.
