For the past three years, Aviator by Spribe has been the undisputed king of crash gaming in the UK. Its formula is almost absurdly simple — a plane climbs, a multiplier grows, you cash out before it crashes — but it works. Millions of UK players log in daily to chase that next 10x or 100x.
Then in June 2026, Pragmatic Play launched Spire+. Same core concept — a climber, a multiplier, a crash event — but executed in a completely different way. A tower instead of a plane. A hidden skull instead of a random crash. Adjustable difficulty from Easy through to Mastery. And a max win of 250,000x that makes Aviator look conservative.
So which should you actually play? We break it down across six categories.
1. The Mechanic — Different Enough to Matter
Aviator is a classic crash game. A plane takes off, a multiplier climbs from 1.00x upwards, and at a random point the plane flies away — the crash. You need to click “Cash Out” before that happens. Miss it and you lose your stake. Time it right and you collect your bet × the multiplier.
Spire+ takes a different angle. You're climbing a virtual tower, row by row. Each row you ascend raises your multiplier. But one row on each level hides a skull — hit it and the round ends instantly (your crash event). You choose which square to step on; the skull is revealed only after you commit. Cash out before climbing further and you lock in whatever multiplier you've reached.
In Aviator, the crash is fully random and happens in real time — you're watching a live number. In Spire+, the crash is hidden information — you're making strategic choices, not just timing reactions. That's a meaningful difference in feel.
Verdict: Neither is better — they satisfy different preferences. Aviator is purer, faster, adrenaline-first. Spire+ feels more like a puzzle-game with crash DNA. If you play slots for the gameplay, Spire+ will interest you more. If you want raw crash action, Aviator is quicker.
2. Difficulty & Volatility — Spire+ Has a Unique Advantage
Aviator has no difficulty setting. The crash point is provably fair and randomly generated — you can't adjust variance. If you want lower volatility, your only lever is staking strategy (e.g. always cash out at 1.5x).
Spire+ does something genuinely new: it lets you choose your difficulty level before playing. The modes run from Easy through to Mastery, with each higher tier placing more skulls per tower row. Fewer skulls = more predictable climbing, lower potential multipliers. More skulls = higher risk, but larger multiplier jumps when you survive.
This matters for bankroll management. On Easy, Spire+ can function almost like a low-variance crash game. On Mastery, it's one of the most volatile arcade games available in the UK market — with the potential 250,000x max win coming from those higher-skull modes.
🗼 Verdict: Spire+ wins this category. The ability to tune your own risk/reward ratio is a genuine feature. Aviator offers no equivalent — your volatility is fixed.
3. Max Win — Spire+ Is in a Different League
Aviator doesn't publish an official max win cap — in theory the multiplier can climb indefinitely before it crashes. In practice, rounds above 100x are rare, and rounds above 1,000x are exceptional. The practical ceiling in most players' experience is somewhere between 50x and 300x on a big round.
Spire+ publishes its maximum win: 250,000x your stake.That's not a realistic expectation in any given session — but as a theoretical ceiling it transforms the jackpot potential. A £0.20 stake at 250,000x would return £50,000.
To be clear: chasing a 250,000x is a losing strategy. These events are extraordinarily rare and require surviving Mastery-level skulls through multiple layers. But for players who enjoy the lottery-ticket appeal of crash gaming, Spire+ offers a headline number that Aviator simply doesn't match.
🗼 Verdict: Spire+ wins on max win potential. 250,000x is class-leading for crash-style games in the UK market.
4. RTP — Aviator Wins (for Now)
Aviator's RTP is a published 97%— one of the highest of any casino game in the UK market. For every £100 wagered on Aviator across all players, £97 is theoretically returned. That's excellent; most slots sit at 94–96%.
Spire+'s RTP has not been confirmed in sources available at launch. Pragmatic Play hasn't published a verified figure yet. This is worth watching — if the RTP comes in below 95%, it changes the maths considerably for regular players.
Until Pragmatic Play publishes the Spire+ RTP, we can't make a fair comparison. We'll update this post when that data is available.
✈️ Verdict: Aviator wins on RTP (confirmed 97%). Spire+'s RTP is unverified at launch — check back here for an update.
5. Social Features — Aviator Wins Clearly
Aviator's live bet feed is one of its most-discussed features. You can see every other player's live bet in real time — their stake, their cash-out point, their wins and losses. A side chat window lets you send short messages. It creates a shared experience that feels closer to a live table game than a standard RNG product.
Spire+ doesn't have this. It's a solo experience — you climb your tower alone. That's not necessarily a weakness (many players prefer no distractions) but it's a meaningful difference if you enjoy watching others play or using the live chat during sessions.
✈️ Verdict: Aviator wins on social features — no contest.
6. UK Availability — Aviator Is Easier to Find Right Now
Aviator is available at virtually every major UKGC-licensed online casino that carries Spribe content — including Mr Vegas, Casumo, PlayOJO, and dozens of others. It's been in the market since 2019 and is now a default listing at most platforms.
Spire+ launched in June 2026. Distribution will grow quickly — Pragmatic Play is one of the most widely integrated developers in the UK B2B space — but at the time of writing, availability is more limited. Check whether your preferred UKGC casino has added it to their games library before committing to Spire+ as your primary game.
✈️ Verdict: Aviator wins on availability for now. Expect Spire+ to catch up by Q3 2026 as Pragmatic Play rolls out to partner casinos.

Our Verdict
- You want the highest confirmed RTP (97%)
- You enjoy watching other players' live bets
- You want a game available at your existing UKGC casino right now
- You prefer fast, pure crash action with no extra decisions
- You want to control your own risk level (Easy through Mastery)
- The 250,000x max win headline excites you
- You prefer a puzzle-style decision mechanic over pure timing
- You're an existing Pragmatic Play fan who enjoyed Mines+
Aviator remains the safer, more proven choice in June 2026. Its RTP is excellent, its availability is near-universal, and its community features are unmatched. Spire+ is a genuinely interesting challenger — the adjustable difficulty system alone is worth exploring — but it's a new game and its full RTP picture isn't yet published.
Our recommendation: start with Aviator at a casino you already trust. Try Spire+ on Easy mode when your UKGC casino adds it — treat it as a complement to your crash game rotation, not an immediate replacement.
