I can't remember the first time I saw a 'sexy' witch if I am being honest. As a child, witches were always thought to be these wizened, grey-haired warty old crones who cackle and spittled and had a hooked nose and evil eyes.

Then the next thing you know, witches have suddenly gone all glamorous and rather hot and the protagonist on Realtime Gaming's popular Bubble Bubble slot, Winnie the Witch, is certainly as strikingly gorgeous as any female cartoon character you'd like to mention.

Clad in her stockings and figure-hugging witches outfit (which doesn't leave a great deal to the imagination and appears to defy gravity at a couple of key points) and with flaming auburn hair cascading down from underneath her witches hat, Winnie is your guide through the game, along with her trusty black cat.

It's important to note though that Bubble Bubble isn't a slot that is somewhat gratuitous about how Winnie looks. Yes, she's a sexy witch, but in truth she's a peripheral figure when it comes to what makes this slot tick and that is the myriad of different bonus features available and a rather enjoyable base game. Let's take a closer look at how this slot shapes up.

The presentation of the Bubble Bubble slot is nicely done in some respects, but I think a little cluttered when it comes to the symbols on the reels. The backdrop of an old churchyard complete with large grey gateposts, gnarled tree roots and the occasional cobweb and gravestone is a perfect setting for the slot and the jaunty music that plays as you play is another positive.

The owl in the tree is a nice touch with its yellow eyes and the moon lit night sky gives the slot a darker feel without it being at all scary. This is more your Scooby Doo slot than your Evil Dead. The main controls of the slot are all at the foot of the screen with an option to increase the speed of spins as well as the usual bet size, Auto Play and Spin buttons.

The problem for me is the reels as the design of the symbols is quirky but they are all rather large and tend to run into one another, which makes discerning the different symbols somewhat more difficult than it should be, especially at first glance, although to be fair, the more you play the slot, the more apparent the differences are between the symbols on the reels.

What's on the reels?

One positive about the symbols on the Bubble Bubble slot is that Realtime Gaming have done away with the usual playing card symbols and instead, you have a number of symbols to do with spookiness, Halloween and general witchcraft on the reels. That includes a spider, a crystal ball, a skull and a rather striking symbol of two candlesticks melting which are morphing into a rather gruesome face. There's a pumpkin with a face carved into it and a cauldron which has something rather sinister looking attempting to escape from it.

The above symbols tend to be the lower value symbols apart from the pumpkin and spell book which offers higher wins. The warty toad, the raven and the black cat are the higher paying symbols on the reels offering up to 1,000 coins for five on a pay line and these high paying symbols also pay out a small amount for landing two on a winning line.

Alongside these main symbols there are a couple of other symbols on the reels which play a key role in the slot and we'll explore them more in the sections below.

Wild features

The gorgeous Winnie the Witch is the Wild symbol in the game and she only appears on the third reel of the slot. However when she does, she will expand across the reels and hopefully give you a chance at landing a bigger value win, or even more wins across a number of pay lines.

Furthermore, when you land a win using the Winnie the Witch Wild symbol, you will receive a Multiplier Bonus on that win which will increase the value of the win to 3x the standard pay out.

Free Spins features

The main Free Spins bonus feature is triggered when you land three or more of the Cauldron symbols anywhere across the reels and when you do you trigger a bonus round which randomly selects one of three games for you to play.

The first is the Great Ghost bonus which sees a selection of Ghost Wild symbols landing on the reels throughout your 20 Free Spins. The second option is the Wild Witches symbol which only offers 9 Free Spins in comparison but during these spins, Winnie the Witch casts her spells to turn one or more adjacent reels completely Wild on each spin, which can lead to some big value wins.

The Bewitched bonus game gives you the fewest Free Spins at 7 and for this bonus you have the lovely Winnie Wild symbol sat on the middle reel for all seven of your spins and she can help you land some decent value wins, although this is the bonus which is most difficult to land some bigger value wins from.

Other bonus features

If on the Wild Witches bonus you only land a win that is 10x your standard stake or less, then the Win-Win feature will trigger and award you with a prize of between 5x to 100x your standard bet at random. If you do not win on a single spin in the Wild Witches bonus round then the bonus win is set at 100x your bet.

This is a nice extra feature on the Wild Witches bonus round which at least ensures that players will win at least 10x their standard stake during their Free Spins.

Best feature of the Bubble Bubble slot

What makes this slot tick is very much the different bonus features you can unlock in the Free Spins bonus round. While the bonus with seven Free Spins offers more consistent rewards, these tend to be lower than what you can achieve on the other bonus games, which are a little more volatile in terms of the rewards you can land.

The Win-Win bonus on the Wild Witches bonus is a great addition and does mean that if this bonus is triggered, you are at least guaranteed a win of 10x your stake, but seeing as this is a higher volatility slot, you really need a win considerably more than that from the bonus features if you are to turn a profit playing the game.

Winnie the Witch is a delightful addition when she appears on the middle reel in the base game, as this is when you can trigger some of the better value wins as she expands the symbol across the reels and gives you a greater chance off a better value win.

What does the Bubble Bubble slot lack?

I think in general the Bubble Bubble slot works very well but the one thing I would have added to the slot would have been the addition of a randomly triggering base game bonus. That is because the slot is a medium to higher variance offering and it can be a good while before you land a bonus game, as such, this can be an expensive slot to play at times and a decent random base game bonus would give you another option to land a better value win.


The Bubble Bubble slot has everything you would expect a top-quality slot to have including good pace and presentation, some outstanding bonus games, a decent sized jackpot to win (which can be increased by a multiplier) and of course a chance to win some high amounts of money as it is a higher variance game. Fans of lower variance slots won't find this too appealing over the short term, but if you play regularly, you can enjoy some sizeable wins and profitable sessions on this cleverly put together game.


  • Presentation: 14 / 20 - There are some positive and slightly negative aspects to the presentation of the slot, through the positives outweigh the negatives considerably. The one issue is the cluttered look of the symbols on the reels and that I feel makes the slot look a little disorganized. However, the music, backdrop, sound effects and animations used throughout the game are all excellent and help lift the presentation markedly.
  • Game-Play: 14 / 20 - The game-play on the Bubble Bubble slot is fun. The facility to increase the speed of the spins makes this game particularly user-friendly for mobile and tablet users and the fact that you have such a wide range of bets available is also a plus. It is a higher variance game however and as such, wins are not as common as on other games and if you are player that enjoys fewer winning spins but when you land a win they are usually of higher value, then this will certainly appeal to you.
  • Bonus Features: 18 / 20 - Without doubt the best aspect of the Bubble Bubble slot is the different bonus features available in the game. The fact that the Wild expands to cover the middle reel when landed is a nice touch as is the 3x multiplier applied to the wins. Furthermore when you get to the Free Spins bonus games, there are three you can access and playing through each of these and seeing the different levels of pay outs you can land from each is also great fun. The Win-Win feature on one of those bonus games also ensures a minimum win amount - again another nice touch.
  • Entertainment Factor: 15 / 20 - It would be easy to think that Realtime Gaming are using the sexy appeal of Winnie the Witch to sell this slot and while she is easy on the eye, in truth there is more in the game-play and the actual slot itself that will appeal to slot gamers. This is a well put together slot which matches a tough base game, with some appealing and very rewarding bonus features and for fans of higher variance slots, they will certainly love how Bubble Bubble plays.
  • Play Value: 10 / 20 - Higher variance slots are never going to score well when it comes to play value as by their nature they do not offer many wins too often, but although this can be a slot which at times seems like it doesn't want to pay out, it can also see you land some sizeable wins too when the bonus games are triggered and as such, that means the overall value isn't as bad as it could have been.
  • Overall 71 / 100 - There's a lot to like about the Bubble Bubble slot, it is fun to play, has some outstanding bonus features, is friendly for mobile and tablet gamers as well as desktop customers and is presented nicely. It is tough to master but that is all part of its charm and what keeps you spinning the reels.

Good Luck!
