Bubble Bubble Slots

The Bubble Bubble trilogy has become one of the most-popular Halloween online slots series. So what makes the game that started it all so special? We'll take an in-depth look at the original Bubble Bubble slots in this review, focusing on its gameplay, graphics, symbols, win potential, features, and RTP. We'll also compare this game to its sequels.

Gameplay

Bubble Bubble features 5 reels and 50 paylines on a 5x3 grid. You form winning combinations by getting at least 2 or 3 matching symbols (depends on the symbol) in a payline. Wins can only happen starting from reel 1 and going right.

Graphics & Atmosphere

This game has a cartoonish look that revolves around Winnie the Witch and her spooky cemetery hangout. Regarding the latter, you'll see a cemetery gate, owl, and gnarled tree branches in the background. Winnie provides further entertainment by appearing on the reels in a cloud of green smoke.

Symbols & Payouts

Regular symbols include candles, a crystal ball, frog-related brew, octopus-related brew, jack-o-lantern, skull, spell book, and spider. Winnie the Witch is the wild symbol, appearing on reel 3 and expanding to help form winning combinations. The Bubble Bubble max win is 3,000x.

Bubble Bubble Slots Features

In addition to expanding, Winnie the Witch multiples wins that she helps form by 3x. Landing 3 or more cauldrons on the reels unlocks the bonus round, where you'll play one of the following features:

• Bewitched - You receive 9 free spins, and Winnie remains a sticky wild in reel 3 throughout the bonus.
• Great Ghosts - You get 20 free spins with random ghost wild symbols. The Great Ghosts will fly over the reels, dispersing 1-9 wilds when this random feature kicks in.
• Wild Witches - This bonus offers 9 free games, and Winnie will turn the two closest reels wild when appearing. You'll have 3 expanding wilds on reels 2, 3, and 4 when this happens. Wild Witches also provides a win-win feature, where you automatically get 100x the total bet if your bonus win is less than 10x.

Betting Options

The 50 paylines are fixed, but you can change your coin size from $0.01 to $0.25. These options create a betting range going from $0.50 to $12.50 per spin. A speed option lets you speed up or slow down spin results, while autoplay keeps the reels going automatically with your chosen wager size.

RTP & Volatility

We don't see a Bubble Bubble slots RTP figure in the info section. RealTime Gaming (RTG) gives casinos the ability to select payout percentages ranging from 91% to 97% Therefore, Bubble Bubble's payback lies somewhere in this neighborhood. Volatility isn't available either, but we suspect that it's medium-to-high based on our playing experience.

Bubble Bubble 2 introduces Winnie's friend, Wanda the Witch, to the series. The result is that you have one more witch available to provide more-frequent wilds and bigger wins. Regarding the latter, this game's max payout is 50,000x the line bet.

Bubble Bubble 3 brings yet another witch, Willow, into the equation. Willow and Wanda appear as expanding wilds in reels 1 and 5. As for Winnie, she's still around and will help you during the Winni Wild feature. The Bubble Bubble 3 max win remains unchanged at 50,000x the line bet.

More on RealTime Gaming

RTG continues going strong after a quarter century in the online gaming industry. It routinely releases new slots, many of which are quite popular at Aussie-, Canada-, and US-friendly online casinos. Some of its successful games include Achilles Deluxe, Desert Raider, Nine Realms, Rudolph's Revenge, Spirit of the Inc, and T-Rex II.

Verdict on Bubble Bubble Slots

Bubble Bubble was, in many ways, a trendsetting Halloween slot upon its release in 2015. It brought several features to the table, including random wilds, expanding wilds, spreading wilds, and a wild multiplier. These extras have made it relevant today, which is why we give it an 8/10 rating. Our only complaint is that the max payout could be higher. You might consider starting with this game for an introduction to the Bubble Bubble series, then moving to the slightly more-complex and higher-paying sequels.
