Altitude Zero review: Gaston's crash game, flight by flight

A duck pilot, a red-and-gold propeller plane and a multiplier that climbs until it doesn't. Here is what Altitude Zero does in one flight, how its two panels change a session, and how it compares with Aviator.

Updated October 29, 2026 · by the editorial team

Altitude Zero is a crash game from Nocturn Play, released on 12 October 2026, in which a multiplier rises from 1.00× while a propeller plane climbs, and you cash out before the plane flies away. Each flight can reach 5,000× the stake.

One flight, from countdown to "Flew away!"

1. Countdown. "Place your bets" appears with a short timer. Set a stake and press Bet. Press it while a plane is already flying and the bet simply waits for the next takeoff.
2. Takeoff. Gaston, a white duck in goggles and a red scarf, lifts off. The number in the middle starts at 1.00× and climbs along a glowing curve.
3. The climb. Each active panel's Cash Out button shows what you'd collect right now. A stake of 2 at 3.50× returns 7.
4. The exit. The plane escapes off the top corner, "Flew away!" appears, and any bet not cashed out is lost. A new countdown starts straight away.

That's the whole loop, and it is quick. The gap between flights is short, which matters for how you budget (more below).

What sets it apart: two panels that don't copy each other

Bet 1 and Bet 2 each have their own stake, quick-stake buttons, auto bet switch and auto cash-out target. That's where the game's tactics live. Nocturn Play's own guide describes a few setups, and we found them useful as starting points:

• Anchor and runner. A larger stake on Bet 1 auto-cashing at 1.50×, a smaller one on Bet 2 left to run toward 5× or 10×.
• Two exits. Equal stakes, targets at 2.00× and 3.00×. Smoother than one bet at 3.00×.
• Auto plus thumb. One panel on a fixed auto target, the other cashed by hand.

None of these change the long-run maths. They change the shape of the session: how often you see a win, and how large the good moments are. Anyone selling you a crash "system" is selling something else.

Is Altitude Zero provably fair?

It uses the method crash players know as provably fair, put into plain words. The crash point is set before takeoff. A check code is published before the round, the flight key is revealed after, and the "Check a flight" panel compares them for you. A green tick means the result was fixed before the plane left and not touched afterwards. You don't need to understand the cryptography; the panel does the comparison.

The coloured ribbon above the sky lists recent crash points (blue for low, purple for mid, pink for big). It's history, not a forecast. Each flight is drawn on its own.

Altitude Zero vs Aviator

Honestly, if you love Aviator you'll be at home within one flight. The difference is mostly character: Gaston tensing as the number climbs and wincing when you miss gives the game more personality than its famous cousin.

Max win: the 5,000× ceiling, read carefully

A flight stops at 5,000×. That is also the ceiling for a bet, and there's a twist: if a plane reaches it, it flies away there, and a bet that hasn't been cashed out is lost. So an auto cash-out target has to sit below 5,000× to pay. On a 1.00 SC stake, the theoretical top is 5,000 SC. Treat it as a cap, not a target.

Playing on Gold Coins vs Sweep Coins

Each session runs in one coin, chosen with the selector at the top of the game, and switching is refused while a flight is in progress. Nocturn Play's sweepstakes page uses Altitude Zero for its own worked example: a player stakes 1.00 SC, cashes out at ×3.50, and 3.50 SC come back, while the Gold Coin balance doesn't move. If the connection drops before a round settles, the stake returns to the coin it came from, never the other one.

Crash games eat balances fast because rounds are fast. On Sweep Coins, we'd size it so your balance covers at least 50 to 100 flights at your stake. With 20.00 SC, that means 0.20 SC per panel, not 2.00. Use Gold Coins to try both-panel setups before moving to SC. If you use auto bet, glance at the stakes every few minutes; it is easy to forget they're running. For how SC balances turn into prizes, our Gold Coins vs Sweep Coins guide covers the basics.

Who it suits

Players who want a decision every few seconds. Aviator regulars looking for a new look. People who like running a careful bet and a bold one side by side. It's a poor match if you want to sit back; for that, a slot like Black Jaguar Temple lets the spin do the work.
