How to Play

We prepared a detailed step-by-step guide to start playing the Bubbles Bonanza slot:

  1. Find the title in the casino’s game library
  2. Launch online slot
  3. Click on the coins button and set your stake from €0.4 to €100
  4. Check the paytable, and change the game settings if you want to
  5. Start spinning the slot manually or automatically

Bubbles Bonanza is a 6x6 cascading-win slot. Winning lines here can be vertical or horizontal and must contain at least 3 matching elements on adjacent reels or rows. Each winning cascade will explode and be replaced by dropped symbol from the above positions, and new elements will drop to these empty positions.

The game doesn’t provide additional bonus rounds and free spins. The game’s only feature is a progressive multiplier, which increases with each winning cascade up to 200x.

Bubbles Bonanza RTP and Volatility

6.7 
The RTP of Bubbles Bonanza is 95.82%, while the slot’s volatility is low.

Despite the big layout (6x6), the slot has only 5 payable symbols. So, winnings don’t vary that much in this game. Most of the time, you will end up with 2x–10x wins, but once in a while, a series of cascades happen to bring good earnings. Long streaks of dead spins are almost non-existent here.

The theoretical return to the player is 95.82%, which is slightly below the industry average index.

Theme

6.7 

Bubbles Bonanza tells you a story about exciting underwater sea life. The whole action happens on the ocean floor with all kinds of fishes, seaweeds, and other species. A colorful, cartoonish game looks really attractive and sends only positive and friendly vibes.

Of course, you will also hear a peaceful underwater tune. There are also some small animations, including bubbles bursting.

There are only 5 symbols in the game. Here is the full list with odds:

  • Green seashell: 0.1x, 0.4x, 1x, 2.5x
  • Seahorse: 0.2x, 0.5x, 1.5x, 3x
  • Crab: 0.2x, 0.5x, 2x, 5x
  • Octopus: 0.3x, 1x, 5x, 10x
  • Pearl: 0.5x, 1x, 5x, 20x

Max Win

7 
The max win in the Bubbles Bonanza is 4,000x the bet.
Getting a big win in Bubbles Bonanza requires a series of consecutive cascades, which increases the progressive multiplier. Achieving the 5th level by landing 5 successive winning iterations brings a 200x multiplier. Of course, it’s also important to have high-paid lines on the board to capitalize on that multiplier.

Overall Rating

6.8

Bubbles Bonanza is an easygoing cascading-win slot without overcomplicated features. Its simplicity and smooth gaming flow are probably two main assets.

The game holds the balance quite well, so you may consider it for bonus wagering.
