Double Bubble Overview

Despite its more recent makeover with the HD version, Double Bubble slots retains its retro look and peculiar style. The game’s logo is similar to logos of fizzy drinks that were sold in the shops in the United States back in the 1960s. The graphics of the game are sharp, colourful and bright while its background is full of translucent bubbles of various shapes and sizes. Double Bubble slots is equipped with 5 reels in three rows and 20 paylines with an option to play as many, or as few paylines, as you like.

Besides having great-looking graphics and illustrations, this Gamesys video slot also consists of wide range of fantastic traditional fruit machine symbols. As with many online slots, the symbols in Double Bubble slots can be divided into groups of low-paying and high-paying symbols.

The game’s low-value symbols include five traditional fruit machine symbols like cherries, watermelons, grapes, oranges, and plums, listed in ascending order. All low-value symbols on the reels of Double Bubble award certain payouts for combinations of three, four, and five matching symbols.

The high-value symbols on the reels consist of five one-arm bandit symbols including red BAR, blue double BAR, green triple BAR, golden bell, Super 7, also listed in ascending order. The single and double BAR symbols award payouts for combinations of three, four, and five identical symbols, while the remaining symbols award payouts for combinations of two, three, four, and five matching symbols.

The additional symbols on the reels of Double Bubble slots include a Bubble Wild symbol which substitutes for all symbols, except the Bonus symbol.

The Game’s bonus symbol is a green bubble with Bonus on its inside. This symbol is used to trigger the Bubble Popper Bonus game.

How To Play Double Bubble

Like most of the video slots, Double Bubble slots offers a vast choice of coin denominations: £ 0.01, £0.02, £0.05, £0.10, £0.25, £0.50, £1.00, £2.00, £4.00, £6.00, £8.00, and £10.00.

When you select your coin size, you control the amount you decide to play across each active payline.

If Lady Luck is on your side, you may receive the highest payout which is an astonishing 20,000x your total bet. So, even if you chose to play with only 1p, you could get a maximum Double Bubble payout of £200.

Before spinning the Double Bubble slots reels, first, you need to set the coin size that you want to bet. Second, you should decide on the number of active paylines. As mentioned above, this number ranges between one and twenty, with one the minimum and twenty the maximum available. You can select your desired number of paylines in three ways:

Press “BET ONE” – an additional line will be added with the lines being reset to one line when you click past the available maximum.​
Select from the coloured numbers – you can also set the number of paylines by pressing the numbers placed on the side of the reel set.​

Press “BET MAX” – this option enables you to play all 20 paylines with the maximum amount available with a single click which sets the reels off automatically.

If you are not too keen on playing with the “BET MAX” option, you can always spin the reels by pressing “SPIN” after you have set the coin size and number of paylines.

How To Win Double Bubble

As with most online video slots, winnings in Double Bubble slots are dependent on which symbols are landed on the reel set and their quantity. Choosing to wager a higher coin-size and play a higher number of paylines will increase your chances of winning. A winning payline is considered only if running in succession from leftmost to right. You can find information on winning combinations and their payouts in the game’s Paytable. All winning combinations and winnings are paid out according to the Paytable.

Double Bubble Bonus Features

The game’s first additional bonus feature is the Double Bubble Wild symbol. This wild symbol substitutes for all other symbols except the Bonus symbol. At the same time, it is the highest paying symbol in the game. If you are lucky enough and manage to land 5 of the Wild symbols across an active payline, you can get the prize of up to 20,000 coins.

The Double Bubble Bonus symbol is a green bubble with “Bonus” written inside the bubble. The Bubble Pop Bonus game is triggered by landing three of the Bonus symbols on reels 1, 3, and 5. During this mini-game, players are given the chance to pop some bubbles and reveal random multiplier winnings. Here you can also win the game’s progressive jackpot, so choose wisely!

There is a green line within the game with BONUS written on it. This is the second bonus feature titled Bubble Line. If any of the symbols appear inside a bubble during the spin of the reels, they will appear on the Bubble line. If these symbols form a winning combo, you will be awarded a multiplier equal to the number of the active paylines.
