Pros
  • Stunning design and immersive gameplay
  • Fun bonus features
  • Smooth gameplay and great betting range
Cons

  • Original Bubble Bubble pointless to play after the sequel got released

It’s no miracle that Bubble Bubble online slot by RTG has accumulated immense attention from players all around the globe. This is one of the online games that has been designed to look more like a thriller and less like a slot machine.

It is amongst the pokies that have above average RTP, standing 96.30%, and a very high volatility. The latter means that you might want to hold back on your bet levels a bit, as your bankroll could fluctuate up and down fast. Bubble Bubble is a five reels and three rows slot, operating on 50 fixed paylines. Bet levels range from $50 – $12.50 per spin, along the lines of most RealTime Gaming pokies. Find out more on this slot and its sequel, Bubble Bubble 2, from our full review.

Theme & Design

Bubble Bubble is set within a graveyard, with the reels almost merging with the creepy background. The game grid is solid black colour, which fits perfectly with the surrounds; namely, spider webs, mushrooms, skeletons, and the entrance of the graveyard. With 3D immersive graphics and the deep, inviting sound effects, Bubble Bubble is a truly witch-themed slot.

The game symbols are all fitting with the theme, whereby Winni the Witch, spiders, a frog, cuddles etc. are thrown into action as the reels spin. Even the controls are themed accordingly, as they are merged with the background. All symbols carry distinct values in Bubble Bubble, which are as follows.

How to Play Bubble Bubble Slot

After you get the feel of the game gird of Bubble Bubble slots, then things are not hard to manage.

  1. First, you must set the bet level by using the two arrows, located in the bottom-centre of the screen.
  2. Then, you can spin the reels using the spider web control. Speed adjustments and autoplay option are also amongst the game features.
  3. After the short animation of the magical reels, the symbols will fix on the reels. Matching 2 high paying symbols, or 3 low paying symbols, on an active payline will result in a win.

Keep in mind that only win is paid from a single payline, while distinct wins from various paylines are summed up and automatically added to your bankroll.

Bubble Bubble Free Spins & Bonus Features

This slot machine does not just offer numerous free games but also the signature Bubble Bubble wild symbol, represented by Winni the Witch. Whenever she lands on the reels, she will expand to cover the whole reel, and then multiplies all wins by 3. The wild symbol of Bubble Bubble even substitutes for scatter symbols, which triggers one of the below features, as long as a minimum of three land on the reels.

Great Ghosts Feature

During this bonus, players will be awarded 20 free spins. As these play out, 1 – 9 ghosts can appear on the reels, turning symbols into wild ghosts. These substitute for all other symbols, and on top of this, the bonus feature can be re-triggered during the 20 free games.

Wild Witches Feature

This bonus feature will unlock 9 free spins, during which the Winni the Witch turns 1 – 2 other reels into expanding wilds. This bonus game can also be re-triggered as it plays out.

Besides the above features, as this bonus feature plays out, the Win Win feature is also operating – awarding spins that do not win a high enough value with a standard prize ranging from 5 – 100x the player’s stake. This value is calculated at the end of the bonus game.

Bewitched Feature

If you trigger this bonus feature, you will win 9 free games, with Winni the Witch remaining on the middle reel until the feature ends. Players can re-trigger the bewitched feature, by landing additional scatters on the reels.

Stats & Mechanics of this Slots Game

Aren’t the bonuses of Bubble Bubble slot fascinating? Well, they are but do not get carried away. This slot is a very volatiline one, which means that wins might take a while to come. On the long run, you will probably be fine, as the return to player rate is very high, at 96.30%.

Watch out for the wild symbols, as these are the key to the maximum win of 3,000x your bet level.

Bubble Bubble 2 Slots

As you might have guessed, Bubble Bubble has been very popular in Australia and the US, and RTG did not take long to release the sequel to the original game. In terms of statistics and gameplay, both Bubble Bubble slots look identical (see more below). When it comes to graphics, however, the sequel is much more colourful and less creepy, while still maintain the original theme.

The twist of this slot is that Wanda joins Winni, operating in exactly the same way. Nonetheless, as a result players can bag 9x wins, amount to a jackpot of 9,000x their bet – which is considerably higher when compared to the original game.

Rest features operate in the exact same way, but the implementation of two expanding wilds is a great addition to this RTG sequel.

Our Verdict

There should not be a question as to whether Bubble Bubble slots are worth playing. They are spectacular games in terms of design, they provide access to multiple bonus features that keep players entertained, and the theme is very intriguing, setting the tone in a similar fashion to a movie. RTG has crafted both Bubble Bubble titles with an intriguing gameplay, a great range of bet levels and decent mechanics.

Probably the only aspect that we did not like about Bubble Bubble is that the 3,000x maximum win is rather low for a high variance slot game. Nonetheless, the sequel offers three times that amount, so we would suggest you to try that one instead.
