The theme is based on the world-famous Double Bubble gum and it features winning symbols such as plums, grapes, oranges, cherries, melons plus a Super 7, bell, 1 bar, 2 bar and 3 bar symbol and of course the Double Bubble Wild symbol.
Whenever a Bubble symbol shows up on the Bubble line area, players have a multiplier winning combination that can multiply their wins by up to 22 times the original wager amount and there are 37 different winning possibilities.
You can play Double Bubble slots completely free (without wagering any money) using the Demo-mode here. Alternatively, you can play for real money betting as little as 1p per payline or as much as £4 for a chance to win some serious cash prizes.
In Double Bubble slots 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.
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.
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?
So never mind the Bubble Pop Bonus, which does produce fantastic winnings on its own, but this Bubble Line bonus is where I got most of my highest winnings, as you can see in the video featured above.
The wild symbols in this slot game is represented by the Double Bubble picture. As with most Wilds in online video slot games, the Double Bubble 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 slot 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.
