Double Bubble from Roxor Gaming: Slot Review - a soapy paradise!

Get ready to pop some bubbles but choose very carefully and a huge cash prize could be all yours!

Ever wondered what would happen if you were to combine a fruit machine slot with lots of bubbles? The result is Double Bubble of course! It’s a fresh take on old school fruit machine slots but with a bubbly twist! This game was released by Roxor Gaming back in 2014 and has just recently been re-released with a fresh new HD updated version.

The slot has 5 reels with 20 paylines and comes with some interesting features such as Bubble Line, Multipliers, and a Bubble Pop Bonus Game.

Special Features

The first feature to highlight is the Wild symbol. It is illustrated by the Double Bubble logo and it substitutes for all other symbols except the Bonus symbol. It is the highest paying symbol in the game and if you are lucky enough to land 5 of these symbols across an active payline then you will be awarded a staggering 20,000X payout!

The Bonus symbol is denoted by a grey bubble with the word “Bonus” inside it. To trigger the Bubble Pop Bonus game then you will need to land 3 of these symbols on reels 1, 3, and 5. In this fun mini-game, you get to select some bubbles to pop in order to reveal random multiplier prizes.

While playing the game, you will notice a green line with the word “Bonus” just below the reels. This is called the Bubble Line feature. If any symbols appear inside of a bubble as you spin the reels then they will appear on the Bubble Line. If these symbols form a winning combination then you will win a multiplier that is equal to the number of active paylines. For example, if you choose to play with 20 paylines, the multiplier will increase to a whopping 22X!

Theme, Graphics and Sound

The game has a very distinctive retro look and style. For instance, the game’s logo looks like it was taken right off a fizzy drink bottle you would find in an American diner in the 1960s. The graphics are bright and colourful and the backdrop of the game is filled with bubbles of all shapes and sizes. Symbols consist of a range of fruit such as melons, cherries, grapes, plums as well as classic symbols such as bells, bars, and lucky number seven. There are hardly any animations to mention except when in the bonus game but the symbols move very smoothly along the reels in a very clean and crisp motion.

The music feels like a carousel tune and it plays each time you spin the reels. It is jaunty and the perfect foil for the thud sounds of the symbols falling into place.

Win lines, Payouts and Jackpots

The game has 20 paylines, a good RTP of 96.02%, and an amazing maximum payout worth 20,000X your stake.

Below is a summary taken from the PayOut Table from the game. The amount won for each combination depends on the value of the bet when you spin the reels.

Bet Range: 0.01, 0.02, 0.05, 0.10, 0.25, 0.50, 1.00, 2.00, 4.00, 6.00, 8.00, 10.00..200.00
