Double Bubble Slot Review

How to play

Double Bubble slot is played on the famous five-by-three grid, with 20 adjustable paylines. Thus, you can select how many paylines you want to play with before you place your bet. The reels have a simple pink and white design with the classic and fruit symbols standing out against the background. The symbols will be explained later in this review.

This video slot's betting range is quite wide, offering both high-roller and lower-budget players a chance to spin the reels. The range stands between €0.20 and €200.

Once you select your coin size and number of paylines, the next thing to do is click on the spin button until you land a winning combination. Your payout will be calculated instantly, and then you can spin the reels again.

You can also click on Bet Max if you want to play with all the 20 paylines and the maximum bet level. If you're going to add another payline before you play, you can select Bet One. Unfortunately, however, there is no autoplay function in this slot.

Symbols and payouts

Double Bubble offers a wide range of classic and fruit-themed symbols that provide payouts ranging from 2x all the way to 20,000x your line bet. The highest paying symbol here is the Double Bubble wild, which pays out 20,000x your line bet when you land five. It also offers 500x, 100x, and 20x your line bet for hitting four, three, or two across the reels.

Next, we have the Super Seven, yellow bell, a green bar, a blue bar, and a pink bar. These five symbols offer payouts of 500x your line bet when you land five, which is a huge step down from the highest paying symbol. They also offer different payouts when you land two, three, or four, ranging from 2x to 200x your line bet.

Double Bubble also features some fruit symbols, which act as the lower-paying symbols of this slot. The plum and orange offer payouts of 200x your line bet for hitting five across the reels. The grape, watermelon, and cherry will also reward you with 100x your line bet for five.

Best Double Bubble bonus feature

One significant Double Bubble bonus is the wild, represented by the logo with the words 'WILD' written beside it. It can replace all the other symbols on the reels (apart from the bonus) and form a winning combination. It is also the highest paying symbol, offering 20,000x your line bet.

The game also offers the Bubble Pop Bonus, which is activated when you land the green bubble symbol on the first, third, and fifth reels. If you land three or more of this symbol, you will be led to a pick-me bonus game. Here, you have the choice of three floating bubbles, and you have to pop one. The one you pick will reward you with a multiplier, and the payout will be instantly calculated.

The final Double Bubble bonus is the Bubble Line bonus. This bonus is continuously being played out during the base game. Underneath the reels, a meter with the words BONUS is spelled out. Whenever a symbol lands on the bubble reels, the meter is filled up. Then, if these symbols form a winning combination, you receive massive cash prizes depending on how many paylines you were playing with.

To the disappointment of many, there are no Double Bubble free spins. This would have made the bonus features and gameplay better, in our opinion.

RTP & volatility

The Double Bubble RTP stands at 96.02%, which is a little bit above average but perfectly acceptable. The RTP is impressive for a classic slot, but the volatility is low, so you should expect small but frequent wins as you play this slot.
