Bubble Bubble 2 slot review

Bubble Bubble 2 slot: what the sequel changed

Bubble Bubble 2 arrived about 17 months after the original and is the middle game of RTG’s witch trilogy, which you can browse in our slot reviews. The format stays familiar, with a 5x3 grid and 50 lines, but the reported math profile is quite different.

In short: the same long-run cost, a bigger listed ceiling and a bumpier ride. The separate bonus game listed for the first title doesn’t appear in the sequel’s feature list, so free spins carry more of the weight. If you want the steadier version, read our Bubble Bubble review.

All figures come from third-party databases such as SlotCatalog’s RTG catalog (opens in a new tab), because RTG’s website couldn’t be reached. Check the game’s help screen for the figures at your casino.

How Bubble Bubble 2 features work

Four features are listed. We describe each in general terms; the in-game paytable gives the exact rules, which our sources don’t include.

• Wild: substitutes for regular symbols to complete wins across the 50 lines.
• Scatter: counts anywhere on the reels and is tied to the free spins round; see our scatter glossary entry.
• Expanding symbols: a symbol grows to fill more of its reel, which can link several line wins on one spin.
• Free spins: a round of spins without a new stake, where much of a high-volatility game’s return tends to sit.

We don’t quote trigger rules, spin counts or how often features land. Those details aren’t reliably published, and the paytable is the only authoritative source.

Bubble Bubble 2 RTP and volatility in plain terms

At 95% RTP, expect to lose about $5 per $100 staked over a long run. High volatility means those losses and wins arrive unevenly: long quiet stretches, then occasional larger hits. A short session can end far from the average, in either direction.

The practical effect is on your budget. High-volatility slots need more spins to give the free spins round a fair chance to appear, so smaller stakes work better on a fixed budget. Our slot volatility guide and what is RTP cover the theory.

Bubble Bubble 2 on a $50 budget

Expected loss is total stake x house edge. Here’s how a $50 budget and 200 spins look at three stakes, assuming each stake is available in the game:

At $0.25, your $50 covers the full 200 spins even if nothing lands. At $1 or $5, reaching 200 spins depends on wins along the way, and on a high-volatility game many sessions won’t get there. Bankroll management starts with that choice.

Bubble Bubble 2 max win vs bonus cashout caps

A third-party table lists Bubble Bubble 2’s max win at 45,000x the bet. That’s $11,250 on a $0.25 spin, $45,000 on $1 and $225,000 on $5. Such results are extremely rare, and most sessions end below the starting balance.

If you play with a bonus, the cashout cap can matter more than the max win. Third-party reviews report a $1,000 max cashout on Planet 7’s WELCOME200 bonus. Under that cap, a win of any size during bonus play would be cut to $1,000 at withdrawal.

Check the cap before you claim. Our max cashout rules page explains how casinos apply them.

Is there a jackpot on Bubble Bubble 2?

No progressive jackpot is listed for Bubble Bubble 2. Casinos can add RTG’s Real Series random jackpots to non-progressive games, and Wikipedia’s RealTime Gaming article (opens in a new tab) notes these can land at random regardless of symbols. If you see a meter, read its rules in the game. More in our progressive jackpots guide.

How to play Bubble Bubble 2 with a slots bonus

Bubble Bubble 2 is a regular video slot, so it normally counts toward slot wagering. A few checks first can save a voided bonus:

1. Read the bonus terms for wagering, max cashout, max bet and excluded games.
2. Confirm Bubble Bubble 2 isn’t on the excluded list; Planet 7’s coupon rules are reported to exclude Banana Jones and Fish Catch, for example.
3. Work out the wagering in dollars: at a reported 30x (bonus + deposit), a $50 deposit with a $100 bonus means $4,500 of spins.
4. Estimate the cost: 5% of $4,500 is $225, more than the $150 balance.
5. Decide whether you’d rather play with cash and no cap. Our bonus vs no bonus page helps.

Slots like Bubble Bubble 2

If the witch theme or the high-volatility profile appeals, try these RTG titles:

• Bubble Bubble 3: the 2021 follow-up, listed at a 96% RTP and high volatility.
• Witchy Wins: witches, 243 ways and random multiplier wilds.
• Spooky Wins: a Halloween slot with a bonus wheel and free spins.

Bubble Bubble 2 vs Bubble Bubble and Bubble Bubble 3

The three witch games share a 5x3 grid and 50 betways but differ in risk and ceiling. Here they are side by side on third-party data, with the average cost of $100 staked at each listed RTP.

Bubble Bubble 2 has the biggest listed ceiling of the three, while Bubble Bubble 3 is the cheapest to play at its 96% listing and adds respins. The original Bubble Bubble is the smoothest ride, with medium volatility and a bonus game.

Bubble Bubble 2 myths to ignore

High volatility makes dry spells longer, which tempts people to believe a feature is ‘due’. It isn’t. Every spin is independent, set by a random number generator. Raising your stake after losses only increases what you put at risk. Read chasing losses if that pattern feels familiar.
