How much can you win in the Bubble Pop Bonus?

When triggered, the Bubble Pop Bonus All your wins will be multiplied by the bet position on the original spin before entering this bubble-pop-bonus Feature mode. Each spin comes with a chance to trigger the Bubble-Pop-Bonus mode. This is activated when the scatter symbol simultaneously appears on the 1st, 3rd and 5th reels.

When this feature is activated it replaces the main slot screen with the exciting Bubble-Pop-Bonus screen which presents you with 3 extra bubbles. To reveal random multiplier value, you will need to select one of these extra Bubbles.

When the Bubble-Pop feature mode is completed, the regular game mode is returned. The prize won in the bonus mode are then summed with your win total. It’s a very straightforward bonus game that awards a win every time; all Bubbles contain a multiplier prize.

How much does the Double Bubble Line Bonus payout?

When triggered, the Double Bubble Line Bonus feature can pay out a cash prize up to 22 times your wagered amount (stake). This additional bonus game which is triggered by lining up the symbols on the reels and the symbols on this In-Line Bonus found on the lower part of the game screen, awards a multiplier winning combination when a bubble symbol show on the bubble-line area.

The Wild symbol in this video slot game, is the Double-Bubble symbol. Therefore, with this wild symbol, you can substitute for all the other symbols, except the bonus symbol, when completing winning combinations. Double Bubble slots is perhaps the most popular video slot developed by Gamesys.

A bubble symbol appearing scattered on any of the 5 reels is put in the second win area known as the bubble line. This area is located underneath the main reels of this slot machine.

If the symbols in the Bubble-Line area produce a winning combination, the winning combination is multiplied by the lines wagered on. For instance, all the possible 20-lines are wagered on, all your winning combination appearing this place is multiplied by a factor of up to 22 times.

What does the multiline feature in Double Bubble mean?

In multi-line slots, you can opt to put your bet on over one pay line. Since wins in slots are realized having identical symbols in a pay line, putting your bets on more lines will boost your odds of winning.

If you opt to put your on more lines, your bet coin value will be compounded by the number of wagered lines.

This feature allows you to select the total number of spins the slot machine will make, you then sit back and wait for the results. However, the game will automatically stop wherever there is a bonus game or upon pressing the stop button. This gives you full control of the game.

If you have ever played at any of the Gamesys casino sites for sure you’ve seen Double Bubble slots. This video slot game features 20 paylines which offer a decent amount of winning combinations without diluting your payouts with a ridiculous amount of paylines like it happens with other 100 paylines slot games.

What the Double Bubble slots RTP (Return to Player)?

The Double Bubble slot game RTP has been set at 96.02% regardless of where you choose to play. In case you’re wondering what RTP means, let’s use an example. If there’s a £100 wagered on Double Bubble, that means there should be £96.02 paid out as winnings, on average.

Typically an online slot that offers an RTP of 95.5% and above is considered to have a good payout rate. Games that fall below this point are considered to be riskier slots with a poor payout rate.

So we’ve reached the end of this Double Bubble slot review and we’ve covered features like the 22 times bonus multiplier, a Pick-a-Box bonus game, a higher than usual RTP and a huge £200,000 single Jackpot payout which make Double Bubble the most popular video slot from Gamesys.

    I’m more of a microgaming slots type of guy but I’ve seen this doube bubble game featured on some uk casinos and i think there’s also a progressive jackpot in some cases… it seems a bit limited in terms of features, like there’s no free spins but i reckon the variance must be attractive and with a £200k single jackpot payout, i would definitely go for it.

  2. Calvin on

    I like the simple gameplay, nice animation and graphics. However I don’t get some of the bonuses.. gives a headache to figure out. It would be good if it loaded faster

      Hi Calvin,
      I had the same situation when I played it the first time. Figuring out how the In-Line bonus works really left me scratching my head but I like playing Double bubble nevertheless.

  3. Mia Moore on

    I love the bonus features of this video slot. I know is confusing tho! The bubble line is basically an extra line but it pays 22x your coin size if you get a winning combination. This Bubble Line is always activated however, there are no symbols on it. The symbols that will appear in this line are those that are circled by a bubble on the regular reels.
