Developed in October 2015 and available across all platforms, Bubble Bubble is a highly entertaining video slot themed around the concept of black magic. Played at five reels and fixed 50 paylines, the Realtime Gaming title features very good visuals and animations, with spooky sound effects helping create an eerie atmosphere on the game screen.

The action revolves around Winni the Witch, a real flirt who has dedicated her life to black magic, so don't be surprised to see her cook up various potions in her cauldron, bubbling away on the fire. With the ceremony taking place at a graveyard by night, you will also see the likes of black cat, black crow, toad, book of spells, Jack-o'-Lantern, spiders, skulls and many other scary-looking items.


We are not impressed by the fixed 50-line format since not all gamers can afford a $0.50 per bet spin, but at least $0.01 is the minimum coin denomination, with $1 being the maximum. Spin or Autoplay can be used to start the game, whereas you also have the option to choose the desired speed of reels between three values.

Pressing Help & Rules takes you to the game's Paytable, which contains plenty of useful information. The first thing you will notice is that Winni the Witch symbol is Wild, appearing stacked on the middle reel to cover all three positions and multiplying all subsequent payouts by x3. Wild also counts once for Scatters.


Being a high volatility slot game, Bubble Bubble will see players heavily rely on extra features in an attempt to turn the profit, and chances are you will enjoy the Wild multipliers, Wild Witches Feature, Great Ghosts Feature and Bewitched Feature, with trademark Win-Win Feature also in place if everything else fails.

Bonus Round

The main bonus round is unlocked when three or more Cauldron Scatters appear left to right. Click on one of the symbols to trigger one of three bonus games.

Wild Witches Feature: 9 free games are played, with Winni the Witch casting spells each time she appears, turning random symbols into Wilds before wins are awarded.

Great Ghosts Feature: 20 free games are awarded, where up to 9 Wild Ghosts fly onto the reels each time any Scatter win (2 or more) is paid.

Bewitched Feature: 7 free games are played, with Winnie the Witch Wild covering reel 3 for the duration of the free spins.

If any of the above features fails to award an amount of 10x total bet or more, Win-WIn Feature will become active, awarding a cash prize of 5-100x total bet.

Scatter Symbol

Scatter is depicted as a Cauldron and its main role is to award entry into the bonus round. At the same time, you will receive an instant credit prize of 2x, 3x, 6x and 33x total bet when two, three, four and five of these occur anywhere. If Wild appears in any of these combinations, said payouts will be multiplied by x3.


There are no progressive jackpots linked to Bubble Bubble slot game, whereas maximum coin jackpot stands at 3,000. You will receive said payout when one or more Wilds replaces for black cat or black crow in a five-of-a-kind combination.


Bubble Bubble also launched on mobile in October 2015, with the HTML5 version, optimized for horizontal play, coming equipped with a full-length game options panel and also deploying fixed 50 paylines.

The visuals and animations do not look as crisp as on desktop computers, but you can still enjoy a rewarding gaming experience on the move, especially if Winni the Witch and those bonus features occur on frequent basis.
