Bubble Bubble 2 Slot Overview
Bubble Bubble 2 is a magical Halloween slot from RTG, which now trades as SpinLogic Gaming. It’s the sequel to the popular Bubble Bubble, and it brings back Winni the Witch. This time, her cheeky sister Wanda joins her to stir up even more trouble.
The game plays on 5 reels with 50 paylines. It’s set in a spooky village under a full moon, with rickety houses, flickering candles and creatures lurking in the shadows. Even so, the cartoon style keeps it fun rather than frightening.
Wild symbols are the big story here. Bubble Bubble 2 has four different wilds, including both witches and a ghost. On top of that, our original review described three free spins modes to choose from. We refreshed this review in October 2026 and checked the key figures against SpinLogic’s own website.
Bubble Bubble 2 at a Glance
| Developer | RTG (now SpinLogic Gaming) |
| Layout | 5 reels, 50 paylines |
| RTP versions | 97.5%, 95% or 91% |
| Wild symbols | Winni Witch, Wanda Witch, Wild Ghost and WILD |
| Scatter | Magic wand |
| Top payout | 50,000 times your bet per line |
| Free spins | Three free spins modes (from our original review) |
| Prequel | Bubble Bubble (5×3, 50 lines) |
Theme and Graphics
Bubble Bubble 2 sits somewhere between spooky and silly. The background shows a crooked old village under a big full moon, with dark woods and candlelit windows. Meanwhile, a mischievous soundtrack adds to the playful mood.
Winni and Wanda steal the show. They’re cheeky, glamorous and full of personality, and they bring the reels to life whenever they appear. As a result, the game feels more like a comedy than a horror story.
The symbols carry on the magic theme. Lower-paying symbols include spell books, potions, voodoo dolls and cauldrons. Above them, you’ll find the witches’ animal friends, such as rats, owls, bats and cats.
Betting and Paylines
Bubble Bubble 2 has 50 paylines across its five reels. Our original review listed a bet of $0.50 to $12.50 per spin. However, SpinLogic doesn’t publish a bet range, and limits can vary between casinos.
The low minimum makes the game easy to enjoy on a small budget. Even so, check the bet settings at your casino before you start, especially if you prefer bigger stakes.
RTP and Max Payout
SpinLogic offers Bubble Bubble 2 in three RTP versions: 97.5%, 95% and 91%. The casino chooses which one you play. That’s a big difference, as a 97.5% version pays back far more over time than a 91% one.
For that reason, always open the game’s help screen before you play. It will show the exact RTP at your casino. Our guide to RTP and online slots explains why this matters in plain English.
SpinLogic lists the top payout as 50,000 times your bet per line. That’s measured per line, not on your total stake, so keep that in mind when comparing it with other games.
Topboss Group tip: RTG casinos often hand out free spins on named games. If Bubble Bubble 2 is part of a promotion, check which RTP version the casino runs first.
Bubble Bubble 2 Symbols
Four Wild Symbols
SpinLogic lists four substitute symbols: Winni Witch, Wanda Witch, the Wild Ghost and a symbol marked WILD. Each one stands in for other symbols to help complete wins. Having so many wilds is what makes this game feel so lively.
Wand Scatter
The magic wand is the scatter. It can land anywhere on the reels. In our original review, three or more wands triggered the free spins.
Animal and Magic Symbols
The animals pay the most among the regular symbols, with bats and cats at the top. The spell books, potions and other magic items pay a little less. Some of the higher-paying symbols can also pay for just two in a row.
Bubble Bubble 2 Free Spins
SpinLogic’s page doesn’t describe the bonus rounds in detail. So, the features below come from our original review. Check the game’s help screen at your casino for the current rules.
Greater Ghosts
Our original review said this mode gave 20 free spins with extra Ghost Wilds, with up to 9 Ghost Wilds on the reels. Landing more wand scatters could add another 20 spins.
Ultra Bewitched
This mode was described as 7 free spins with an expanding wild on every spin. It could also be retriggered by landing three or more scatters.
Wilder Witches
This mode gave 9 free spins. Each time a witch appeared, she cast a spell that turned more reels wild. Our original review also mentioned a Win-Win feature, which topped up your prize if the round paid less than 10x your bet.
| Mode | Free spins | Main extra |
|---|---|---|
| Greater Ghosts | 20 | Extra Ghost Wilds |
| Ultra Bewitched | 7 | Expanding wild every spin |
| Wilder Witches | 9 | Witches turn reels wild |

- Set your stake: choose your bet using the controls.
- Check the RTP: open the help screen to see which version your casino runs.

Bubble Bubble vs Bubble Bubble 2
The original Bubble Bubble is still listed by SpinLogic too. Both games share the same witch and the same 50 paylines. Here’s how they compare on SpinLogic’s own pages:
| Feature | Bubble Bubble | Bubble Bubble 2 |
|---|---|---|
| Paylines | 50 | 50 |
| Free spins trigger | Scattered cauldrons | Wand scatter |
| Witches | Winni | Winni and Wanda |
| Wild symbols | Not listed | Four |
In short, the sequel adds a second witch and more wilds. If you enjoyed the first game, Bubble Bubble 2 is a natural next step.
What We Changed in This Review
- RTP: we used to quote a fixed 96%. SpinLogic now lists three versions: 97.5%, 95% and 91%.
- Developer name: RTG now trades as SpinLogic Gaming, so we’ve added that.
- Free spins details: we’ve kept the three modes from our original review, but marked them clearly because SpinLogic doesn’t describe them.
Where to Play Bubble Bubble 2
Bubble Bubble 2 is an RTG game, so you’ll find it at RTG casinos. Our original review mentioned it was popular at Roaring 21 Casino. Our guide to RTG slots and casinos lists more sites to try. Lobbies change, though, so check the game is there before you deposit.
Pros and Cons

Cons

Our Verdict
Bubble Bubble 2 is a playful, wild-packed sequel that RTG fans will enjoy. Winni and Wanda give it plenty of charm, and the four wilds keep the base game busy. Just make sure you check the RTP, because the 91% version is a real step down. If your casino runs the 97.5% version, it’s a great Halloween pick.
