What is Astronaut?
Astronaut is Red Tiger Gaming’s crash title, released in 2023. It differs from the standard crash format in two significant ways: it uses a grid-based progression system rather than a single climbing multiplier, and it carries a variable RTP that can reach 99.38% — the highest of any crash game on the market.
The variable RTP is the headline figure. Most crash games have a fixed RTP set by the developer. Astronaut’s RTP is configurable by the operator within the 96%–99.38% range, meaning the version you play depends on the casino you’re at. At 99.38%, the house edge is 0.62% — closer to blackjack than to most casino games.
How to Play Astronaut
Astronaut uses three symbol types that replace the standard single multiplier:
- Green Crystal — advances the astronaut through the grid, increasing the multiplier
- Golden Shield — provides partial protection (exact mechanic varies by round configuration)
- Red Crystal — the crash event; ends the round and loses the bet if uncashed
As the astronaut progresses through the grid, the multiplier increases. You cash out at any point to lock in the current value. The further the astronaut travels, the higher the multiplier and the higher the risk of hitting a Red Crystal.
Auto cashout sets a target grid depth at which you collect automatically. Autoplay cycles through rounds with your current settings applied.
The Variable RTP — What It Means for Players
The 96%–99.38% RTP range is set at the casino level, not visible in-game. This has a direct impact on expected returns:
| RTP | House Edge | Expected loss per €1,000 wagered |
|---|---|---|
| 99.38% | 0.62% | €6.20 |
| 98% | 2% | €20 |
| 97% | 3% | €30 |
| 96% | 4% | €40 |
To find out which RTP your casino is running, check the game’s information panel — reputable operators display the active RTP. If it’s not shown, assume the minimum (96%) and adjust accordingly.
At maximum RTP, Astronaut is the best mathematical proposition in the crash genre by a significant margin.
The 50,000x Ceiling
At 50,000x, Astronaut has the highest hard maximum multiplier of any crash game reviewed here — above Red Baron’s 20,000x and High Flyer’s 1,000,000x (which is theoretical rather than a practical target). On a €1 stake, that’s €50,000. The low maximum bet (€40) limits absolute returns for high-stakes players.
Availability
Red Tiger Gaming is part of the IGT/Everi network, giving Astronaut strong distribution at licensed European operators. It’s available wherever Red Tiger content is carried, which covers most major regulated casino platforms.
Verdict
Astronaut’s variable RTP is a genuine differentiator. At 99.38%, it’s the best house edge available in crash gaming — and the 50,000x ceiling adds real upside. The grid-based mechanic takes some adjustment for players used to the standard format, and the low max bet caps absolute winnings. The critical question is always which RTP your specific casino is running: at 96% it’s ordinary, at 99.38% it’s the best mathematical choice in the genre. Check before you play.
