Bonus Bubbles Online Slots

It's time to get wet 'n' wild with this fintastic seaside soiree of a mobile slots game from Mr Spin casino. Bonus Bubbles won’t leave you feeling washed up... in fact, you could be squids in as there's a treasure trove of multipliers to be won.

Bonus Bubbles features 15 winlines, a minigame with mega multipliers waiting to be won, and a huge progressive jackpot just waiting to be won. Can you make a splash with this Mr Spin exclusive mobile slots game?

Getting Started with Bonus Bubbles

Life’s a beach with Bonus Bubbles, and Mr Spin’s made it as easy as one, two, sea to play this exclusive mobile slots game. To get started, 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 Online Slots

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 are added together to form your total win, with only the highest win paid on each line.

Wild Symbols

You’re shore to love when our Wild symbols get washed 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 a feature win is achieved in Bonus Bubbles mobile slots, you’re given the opportunity to dive on in to the gamble feature or stick with your current win. Y

ou can set which wins you'd like to gamble, if any, and once activated this gamble feature gives you the chance to boost your winnings, but you could lose the lot!

If you enter the gamble feature and decide you don't want to risk your winnings, simply tap 'Collect' and you'll receive your original win value and return to the game reels.

It cannot be entered with a Jackpot win, or any win over £1000.
