Witches will always provide a great theme for online slot games. Clearly, RTG is aware of this, and chose to create the offering known as Bubble Bubble. However, forget any thoughts of a haggard old woman with warts on her nose and crooked fingers. The witch that takes centre stage in this slot game brings nothing but sex appeal to the reels. Don’t be too enticed by her good looks though, because she’ll just as soon turn you into a mouse. Bubble Bubble is perhaps one of RTG’s more famous slot games, featuring wonderful graphics upon its reels to tell the story of the witch. She’s not the only character to show up in the game, though. Instead, she’s joined by various other Halloween-esque symbols. These include a book with the title ‘Love Spells’, a toad to turn into a prince, a black cat, a vial of purple liquid, a skull candle and much more.

The slot itself provides players with a layout that features five reels and three rows in total. This operates as a standard video slot interface, and RTG has also taken the opportunity to include a set of 50 paylines for you to bet on. These lines are not customisable, so you’ll always be betting on such an amount, however, you do have the possibility of altering the bet that you place on them. Simply use the up and down arrows to select between bets of 50p and £250 per spin. There’s also an autoplay function that you can use at your own convenience.

Special Features


The witch symbol, who has the name of Winnie, will operate as this game’s wild icon. This means that wherever she appears on the reels, she will substitute for all of the standard symbols in the game. This can be quite helpful when it comes to creating winning combinations across the reels.

Yet, that’s not her only perk. If she appears on the third reel of the game she will expand across it in its entirety. Imagine the magical wins you can create with a totally wild reel in effect.


Bubble Bubble’s scatter icon comes in the form of the image of a cauldron. This one can show up in any location on the reels and still ensure that you receive a pay-out.

If you spin three or more of this one into view then it will also activate one of three different special bonus rounds.

  • Bewitched Feature – If the scatter symbol manages to trigger this round you’ll be given 7 free spins to play through. Winnie remains in action on the third reel operating as a completely wild reel, therefore, on every free spin that you get during this round, there’s the potential to make bigger and better wins thanks to her.
  • Great Ghost Feature – Triggering this bonus round will offer up 20 free spins, and this also has the potential to see up to nine wild ghost symbols come into operation per spin. Naturally, the more wilds there are in view, the better your chance of creating wins.
  • Wild Witches Feature – And finally, the scatter has the potential to trigger this bonus round which consists of nine free spins in total. On every spin, Winnie will cast a spell for you, and this has the potential to turn one or two of the reels into complete wilds. There couldn’t be a better way of forming huge prizes, could there?

Clearly, Bubble Bubble aims to please its audience thanks to the imaginative graphics and great execution of its theme. RTG clearly has the right idea with this one. Free spins will always be appreciated by slotters, and with this one containing three different types with their own special perks we’re certain that it’s going to remain popular for a long time. Combine this with the wild and potential for a wild third reel during base gameplay, and Bubble Bubble stands out as quite the entertaining offering.
