Getting Started

Life’s a beach with Bonus Bubbles, and Mr Spin’s made it as easy as one, two, sea to play this exclusive online slots game. To start, tap the ‘+’ and ‘-‘ buttons to increase or decrease your total bet and the number on win lines you’re playing on. Ready to play? Just tap the ‘Spin’ button and watch those bubbles bust into life.

Your cost-per-spin amount is calculated by multiplying your bet amount to the number of win lines you choose to play on. This means you can swim to your own tuna with Bonus Bubbles and set your bet to suit you. For example, a 50p bet on 5 of our fin lines would result in a total bet of £2.50. Or betting £1 on all 15 lines, would see your total bet amount total £15

Want to dip your toes in? The minimum bet on this game is a mini-school 2p a line, while the maximum is £20 a line.

If sitting back and enjoying the wildlife is more your thing, Mr Spin has included a handy ‘Auto Spin’ feature that’ll keep you swimming. Set the number of spins, minimum credit level or maximum win amount, and hit ‘Start’. The reels will spin through the number of spins you set at your previous bet amount until you hit ‘Stop’, or you play through them all.

How to Play

Beachy keen to get playing? Set your bet amount, tap ‘Spin’ and watch the tide roll in and stop at random.

When you line up a winning combination of crustaceans and critters on an active winline to be in for somefin special, with Bonus Bubbles wins calculated from left to right! What those winning combinations are depends on the symbols, with some paying out with a 2+ combination and others with 3 or more. Any on-reel winnings will be highlighted on screen before they’re added to your total credit.

Reel Wins

You’d be cray-sea to miss out on Bonus Bubbles as you’ll get a fintastic multiplier of your bet per line for each winning. This will depend on the symbols lined up, so swim on over to the paytable in-game for more information. All wins across multiple lines combine to form your total win, and only the highest win counts on each line.

Wild Symbols

You’re shore to love when our Wild symbols wash up on your win lines, as they substitute for every symbol except the mini-game and Free Spins symbols, helping to make a swimming combination!

For example, line up two K clownfish and a Wild to shellebrate a win that is the equivalent of three of the K symbols.

Mini-Game

There’s no time for clownfishing around in the mini-game, Fish Feed. Spin 2 or more symbols on any of the 15 active win lines to enter. The game itself is simple: spin the reels to feed the fish and build up those multipliers.

You enter the game with three spins, but can win extra ones in the mini-game depending on if the tide is on your side. Land on an “x” symbol though, and you don’t win a multiplier on that specific reel. Fish Feed will end after a player has used all of the awarded bonus spins. Can you make a splash and maximise your multipliers?

Gamble Feature

Whenever you have a feature win in Bonus Bubbles mobile slots, you’ll have the opportunity to dive on in to the gamble feature or stick with your current win. This feature gives you the chance to boost your winnings – or lose the lot. You cannot enter this feature with a Mega Jackpot win, or any win over £1000.

Bonus Free Spins

You’ll make a splash if you line up three or more Free Spins symbols!

3x free spin symbols gives you 5 free spins, 4x symbols will give you 7 free spins, and 5x symbols will see you bagging 9 free spins! These free spins will lock to the same value of your last spin.

Progressive Mega Jackpot
