Get a taste for juicy wins from the Double Bubble online slot. Grapes, oranges, and watermelons feature on the 5 reels and 20 lines, and if any symbols land within a bubble, your bankroll could be bursting with big payouts.

A Bubble Line feature multiplies symbol values by up to 22x, while a special bonus symbol unlocks a bubble popping game with guaranteed wins at USA online casinos. Extra prizes could be yours as a wild symbol steps in for others to compete combinations. The bright colors and simple gameplay have made this one of the biggest games at desktop and mobile casinos. 

It’s the work of Roxor Gaming and it’s such as hit that several other slot games and even a Bingo game have been developed around the same theme. The Double Bubble slot has a high volatility and average returns of 96.02%. You can win 22,000x the stake from the perfect combination of symbols and multipliers as you play this massively popular game at the best online casinos.

The graphics are simple, but clear and colorful, with traditional fruit symbols joined by golden bells, a blue 7, plus single, double, and triple BAR icons. The BAR symbols look like soap to cleverly link with the theme of soapy bubbles that fill the background and trigger one of the bonus features. 

You can enjoy this soapy dish on PCs, iOS, Android, and Windows mobiles for between 0.01 and 20.00 per spin. That’s a range of 0.01 to 1.00 on each payline and you can play any number of lines. It’s always best to activate all available paylines, just so you don’t miss out if a valuable combination lands on an inactive line. It’s even more important here, as the Bubble Line bonus only pays the maximum prize when every part of the game is active.

Click the 3 little dots above the reels, followed by the Game Info tab to see how the Double Bubble online slot works. This table also has a list of symbol values, and you win whenever 3, 4, or 5 matched symbols land across a payline from the left. The game logo is a wild symbol that can act as others to help complete wins, and also pays the most, at up to 1,000x the stake.

A special Bubble Line system places random symbols within bubbles on the Bubble Line that sits below the main reels. It works like a normal payline but the symbol values are multiplied by the number of lines in play. If you have just a single line active the multiplier is 1x, and with 2 lines in play the multiplier is 2x and so on. If you have all 20 paylines active, the Bubble Line multiplier gets a boost to 22x!

The Bonus symbol on reels 1, 3, and 5 starts a Bubble Popper mini game. Simply tap bubbles to reveal a random prize.

A full Bubble Line of game logo symbols with all lines in play will add up to a win of 22,000x the stake. That’s 440,000.00 if you play at the maximum wager of 20.00.

Double Bubble has a high volatility, so it tends to pay out less often than lower volatility games, but the prizes can be higher, which often makes up for this. Just be sure that your bankroll can take the ups and downs that come with high variance gaming. 

Taken as a long-term calculation, the return to players percentage of the Double Bubble slot machine is 96.02%. That means for every 100.00 in wagers, it pays out 96.02 in prizes, but like the volatility, this can vary widely over the course of a session on the game.

It’s easy to see why the Double Bubble online slot is so popular. It bursts with color and uses classic symbols that everyone is familiar with. There are no free spins or respins features, but the Bubble Line and Bubble Popper game can trigger quite often to add extra excitement to any spin.

It’s so popular that a whole range of Double Bubble slots are available, including Triple Jackpot, Megaways, and Fizz versions. You can join the huge number of Double Bubble slot fans as you play it alongside many other hits at the best casino sites with the best casino bonuses featured here.
