How to Play the Bubble Double Slot

Although the Bubble Double Slot has 243 paylines on each spin, this is not an adjustable value. Therefore, your sole concern is choosing the right bet size and then bursting the bubbles by hitting “Spin.” Links to both of these commands are found within the control panel, identifiable through the “New Bet” and “Play” buttons.

The Bubble Double slot online has an auto-spin option that allows you to pop those bubbles without tapping anything at all. With that said, you can only trigger as many auto-spins as your balance covers, so bear this in mind.

Bubble Double Slot Bonus Features

If you examine the growing number of top-tier slots in our game reviews, you’ll notice that many offer Free Spins. Sadly, such a feature isn’t available in the Bubble Double Slot Game. But this is offset by a bit of an overhaul of how the Wild symbol works. Allow us to explain.

Wild symbols can drop in on reels 2, 3, or 4, and whenever they do, they will automatically expand to fill the whole reel. The more you land, the bigger the respective multiplier is, starting at 2x and increasing from there. 

Symbols and Gameplay

You won’t find many online slots that are more colorful. Vibrant yellow, blue, green, pink, and other colors are used to create an explosion of immersive symbols. And when you get the reels moving, the music is almost celebratory. It makes you feel like a winner before the outcome of each spin is known.


There are enough incentives and stimulating features to justify taking a spin on the Bubble Double slot. To see for yourself how great this game is, you’ll need to get involved. Gain access by signing up here.
