How to play
Wins are paid out for matching specific symbols along a particular Payline.
Coin sizes here range from a penny to a tenner, and there’s a maximum bet of £200, plus a top-line payment of 20,000 coins.
You can edit the number of Paylines you play with, up to a maximum of 20 using the Bet One tab. Bet Max automatically picks all 20 lines. However, you do have to click through all of the Paylines to reach the number you want to play, and if you have overshot, you’ll have to go through the whole thing again.
Clearly, playing the maximum number of Paylines will allow you to aim for the big wins while boosting your chances of a bonus game.
There’s no Autoplay function, but Double Bubble is compatible with mobile devices for on-the-go play.
In keeping with the cute retro concept, symbols are bars, bells and fruit including plums, melons, grapes, cherries, oranges and lemons. The highest-paying icon is the Lucky 7, and you get a x500 payout for five of these on a Payline. The fruit symbols offer smaller rewards.
Double Bubble Jackpot special features
The Wild symbol (the game logo) replaces all others, apart from the bonus icons, to complete wins. Land five Wilds on one Payline to get the highest payout, of 20,000x coin size for matching five. Four pays 500x bet, three 100x and two 20x.
Bubble Line bonus
Get five symbols in bubbles to bag the prize here – it’s an x22 multiplier of your wager when you play with all 20 Paylines. Otherwise, the multiplier is equal to the number of lines you’ve played.
Any symbols which appear within a bubble are placed in the second win area, along the Bubble Line. As with a standard Payline, this pays out from left to right.
Bubble Pop bonus
Land three bonus symbols on Reels 1, 3 and 5 to launch this round. It could see you win the progressive jackpot.
In this round, all wins apart from the progressive jackpot are multiplied by the size of your coin bet.
The second version of Double Bubble Jackpot was created, featuring a progressive jackpot of more than £20,000. Then in 2019, a third version was produced offering Mini, Major and Grand progressive jackpots. The jackpot continues to grow until one lucky player scoops it.
Return to Player (RTP)
RTP, or the amount paid to players relative to the volume of wagering on the game, isn’t too shabby in Double Bubble Jackpot. It varies from 95.75% to 96.24%.
You may find the set-up of this game rather basic, but there should still be enough here to retain your interest, whether you’re a high roller or a lot more cautious. There’s also a pleasantly gentle feel to this game.
