Why Slot Stats Matter More Than Names
Most players choose slots based on what they recognise.
It might be a game they’ve seen advertised, one a friend mentioned, or just a title that looks familiar from scrolling through a casino lobby. Names like Starburst, Book of Dead or Big Bass Bonanza carry weight, and that often drives the decision more than anything else.
The problem is that those names don’t tell you much about how the slot games actually play.
Two slots can look equally popular on the surface, but behave completely differently once you start spinning. One might pay small amounts regularly, while another can go long stretches without much happening before suddenly hitting a bigger win. Both can feel completely different, even if they sit in a similar RTP range.
That’s where the stats come in.
Looking at things like RTP, volatility and max win gives a much clearer picture of what to expect. Instead of guessing how a game might play, you can start to understand the style behind it.
In this guide, we’ve taken six well-known slots and broken them down on paper. The goal isn’t to crown a “best” game, but to show how different popular slots really are once you look beyond the name.
💡 Popular Doesn’t Mean Similar
Two popular slots can have completely different RTP, volatility and win potential.
Looking at the stats gives a much clearer idea of how a game actually plays.

⚖️ Same RTP, Different Experience
Most of these slots sit around 96% RTP, but they play very differently.
Volatility and features have a bigger impact on your session than RTP alone.
Starburst (NetEnt) – Low Risk, Low Reward
Starburst is one of the most recognisable NetEnt casino slots out there, and it’s often used as a reference point for how lower volatility games behave.
On paper, the stats are fairly straightforward. The RTP sits at 96.09%, which is right in the typical range for online slots. Where it really stands out is volatility, which is firmly on the low side.
That translates into frequent small wins. You’ll see regular returns, often triggered by the expanding wilds feature, but the payouts are usually modest. It’s rare to see anything close to a big win compared to more modern slots.
From a player experience point of view, this makes Starburst feel steady. Your balance tends to move slowly rather than swinging up and down dramatically. That’s why it’s often seen as a game for longer sessions rather than chasing big payouts.
The trade-off is clear. You get consistency, but not much in the way of high win potential.

✔️ What Starburst Tells Us
High RTP doesn’t always mean big wins. Starburst pays often, but in small amounts.
This is a classic example of a low volatility slot focused on steady play rather than big payouts.
Book of Dead (Play’n GO) – High Risk, Bonus-Driven
If Starburst represents steady, low-risk gameplay, Book of Dead from Play’n Go sits at the opposite end of the scale.
The RTP is slightly higher at 96.21%, but that doesn’t tell the full story. This is a high volatility slot, which means wins are far less frequent, but the potential payouts are much larger when they do land.
Most of the game’s value is tied to the free spins feature. During this round, a single symbol is chosen to expand across the reels, which can lead to very large wins if it hits correctly. Outside of that, the base game can feel quiet, with long stretches where not much happens.
That’s what gives Book of Dead its reputation. Sessions can feel slow or even frustrating at times, but one good bonus round can completely change the outcome.
Compared to Starburst, it’s a very different experience. Instead of steady returns, you’re trading consistency for the chance of a much bigger hit.
👉 For a full breakdown, see our Book of Dead slot review.
⚖️ What Book of Dead Shows
Two slots can have similar RTP but feel completely different to play.
Book of Dead is built around big bonus potential, not frequent wins.
Gates of Olympus (Pragmatic Play) – High Volatility with Multipliers
The Pragmatic Play slot, Gates of Olympus is a good example of how newer slots approach volatility and win potential.
The RTP is typically listed around 96.50%, although this can vary depending on the casino. Like Book of Dead, it’s a high volatility game, but the way it delivers that volatility is very different.
Instead of relying on a single bonus feature, Gates of Olympus uses multipliers and tumble mechanics. Wins can chain together within a single spin, and multipliers can build up quickly, especially during the free spins round.
This creates a more dynamic feel. You might go several spins without much happening, but when the game does connect, wins can escalate quickly. It’s less about one big moment and more about stacking potential within a feature.
That said, it still comes with the same trade-off as other high volatility slots. Long quiet periods are common, and not every bonus round will deliver a big return.
Compared to Book of Dead, it feels more active and modern, but the underlying risk is still there.
👉 For a full breakdown, see our Gates of Olympus slot review.
⚡ What Gates of Olympus Shows
High volatility doesn’t always mean one big win — it can come from stacked features and multipliers.
Modern slots often spread risk and reward across multiple mechanics rather than a single bonus round.
Sweet Bonanza (Pragmatic Play) – Medium-High Volatility with Tumbles
Sweet Bonanza sits in a similar family to Gates of Olympus, but with a slightly different feel.
The RTP is usually around 96.48%, though like many Pragmatic Play slots, it can vary depending on the casino. In terms of volatility, it’s generally considered medium to high, meaning it still has big win potential but tends to feel a bit more active than fully high-volatility games.
The key mechanic here is the tumble system. Winning symbols disappear and are replaced within the same spin, creating the chance for multiple wins without placing another bet. Combined with multipliers in the bonus round, this can lead to large payouts building up over a single sequence.
Compared to something like Book of Dead, it feels less reliant on one single moment. There’s more happening during regular play, even if the biggest wins still tend to come from the free spins feature.
It’s a good example of how modern slots try to balance engagement with win potential, giving players more to watch while still keeping that high ceiling in place.
👉 For a full breakdown, see our Sweet Bonanza slot review.
🍬 What Sweet Bonanza Shows
Modern slots often mix steady action with high win potential through mechanics like tumbles.
It creates a more engaging experience, even if big wins are still tied to bonus features.
Big Bass Bonanza (Pragmatic Play) – Medium Volatility and Feature Collection
Big Bass Bonanza is one of the most popular slots in the UK, and part of that comes down to how approachable it feels compared to some of the higher-risk games.
The RTP is usually around 96.71%, although again, this can vary slightly depending on the casino. In terms of volatility, it sits closer to medium, which makes it more balanced than games like Gates of Olympus or Book of Dead.
The gameplay is built around a collect-and-expand feature during free spins. Landing fisherman symbols collects values from fish symbols, and hitting enough of them unlocks additional free spins and multipliers.
This structure gives the game a clear sense of progression. Instead of relying purely on one big moment, wins build through the feature, which keeps players engaged without needing constant big hits.
Compared to Sweet Bonanza, it feels more structured and predictable. Compared to Starburst, it still offers much higher win potential.
It’s a good middle ground. Not as steady as low volatility slots, but not as extreme as high volatility ones either.
👉 For a full breakdown, see our Big Bass Bonanza slot review.
🎣 What Big Bass Bonanza Shows
Medium volatility slots often balance regular play with meaningful bonus potential.
Feature progression can make wins feel more structured rather than relying on one big moment.
Mega Moolah (Games Global) – Jackpot Slot, Completely Different Model
Mega Moolah is a very different type of slot compared to the others on this list.
Originally developed by Microgaming, it’s now part of the Games Global portfolio following the transfer of Microgaming’s game catalogue. A lot of players still associate Mega Moolah with Microgaming, so you’ll often see both names mentioned.
On paper, the RTP can vary quite a bit, typically sitting anywhere from the high 80s to mid-90s, depending on the version and how the jackpot contribution is factored in. That’s noticeably lower than most standard slots, but there’s a reason for it.
A portion of each spin goes towards funding the progressive jackpot, which can reach into the millions. That’s where the game’s appeal lies. It’s not designed for steady returns or frequent wins, but for the chance of a life-changing payout.
Because of that, Mega Moolah is considered very high volatility. Long dry spells are common, and most sessions won’t see anything close to the jackpot. The RTP reflects the overall return across all players, including the rare jackpot winners.
Compared to the other slots in this guide, it operates on a completely different model. You’re effectively trading a lower average return for a shot at a much bigger prize.
👉 For a full breakdown, see our Mega Moolah slot review.
💰 What Mega Moolah Shows
Jackpot slots work differently from standard games, with part of each spin funding the prize pool.
Lower RTP is the trade-off for the chance to win a much larger payout.
What These 6 Slots Tell Us About RTP and Volatility
Looking at these six slots side by side, a few things become pretty clear.
First, RTP alone doesn’t tell you how a slot will feel. Most of the games here sit around the 96% mark, yet the experience varies massively.
Starburst plays nothing like Book of Dead, and Mega Moolah is in a completely different category altogether.
That’s where volatility becomes the deciding factor. Low volatility games like Starburst offer steady, smaller returns. High volatility games like Gates of Olympus or Book of Dead can feel quiet for long stretches but carry much higher win potential. Medium volatility slots like Big Bass Bonanza sit somewhere in between.
Another takeaway is how much modern mechanics influence gameplay. Tumbles, multipliers and feature progression systems have changed how wins are delivered. It’s no longer just about hitting a payline. The way a slot builds wins has become just as important as how much it pays overall.
Then there’s the difference in slot types. Standard slots and jackpot slots operate on completely different models. Mega Moolah shows how RTP can drop significantly when part of each spin is used to fund a progressive jackpot.
Put all of that together, and one thing stands out.
👉 Choosing a slot based on its name alone doesn’t tell you much.
Understanding the stats gives you a much clearer idea of what you’re getting into, whether that’s steady gameplay, bonus-driven volatility or a long-shot jackpot chase.
💡 The Key Takeaway
Most popular slots have similar RTP, but play very differently.
Volatility, features and game type have a bigger impact on your experience than RTP alone.
