Every crash game needs a thing that climbs. Aviator has a plane. Spaceman has a cartoon astronaut floating through space. And 100HP Gaming’s Astronaut has — an astronaut, climbing through space until it crashes. The theme is familiar by design. What makes Astronaut worth understanding is not the visual, but the distribution engine behind it: this is one of the most widely deployed crash games in emerging markets, and in India alone it has been reported to generate over a million dollars in monthly revenue.

This guide covers how Astronaut plays, what its RTP means, how its provably fair system works, and where it fits against the bigger names in the category.

What Astronaut is

Astronaut is a curve-based crash game from 100HP Gaming. The structure is the canonical crash format: a multiplier starts at 1.00x and rises continuously. An astronaut ascends alongside it. At a randomly determined point the astronaut crashes, and the multiplier stops. If you cashed out before the crash, you win your bet times the multiplier at that instant. If you did not, you lose the bet.

There are no lanes to cross, no partial exits, no side features. Astronaut is a clean, conventional implementation of the mechanic that Aviator made mainstream. Its edge is not novelty — it is reach.

How Astronaut works

The round loop is the same one that defines the whole category:

  1. Place a bet before the round starts. Many operators allow two simultaneous bets, letting you set two different cash-out targets in one round.
  2. Watch the multiplier climb from 1.00x as the astronaut rises.
  3. Cash out at any point to lock in your stake times the current multiplier.
  4. Or crash. If the round ends before you cash out, the bet is lost.

Most versions support auto cash-out: you pre-set a target multiplier, and the system exits automatically when it is reached. This is the single most reliable way to hold your discipline, because it removes the in-the-moment hesitation that causes players to blow past their intended exit.

The crash point is decided by a random number generator before the round is displayed — not while it plays out. Nothing you do during the round influences when it crashes.

RTP: 97% and what it costs

Astronaut’s commonly reported RTP is around 97%, matching the standard crash-game benchmark set by Aviator. At 97%, the expected loss is roughly $30 per $1,000 wagered over volume.

As always, treat that as a headline figure to verify rather than a fixed guarantee. Operators can run alternative RTP configurations, and the in-game information panel is the authoritative source for the version you are actually playing. RTP is also a long-run average — it says nothing about the variance of any single session, which is governed by the game’s volatility.

Provably fair: the trust layer

Astronaut uses a provably fair system. Before each round, the game commits to a result via a hashed seed. After the round, the seed is revealed, and any player can recompute the hash to confirm the crash point was fixed in advance and not altered mid-round.

This matters more than it might sound. In markets like India and Brazil — where much of Astronaut’s player base sits — players actively verify fairness, and a credible provably fair implementation is a genuine trust and adoption driver, not just a compliance checkbox. A game without it starts at a disadvantage in exactly the markets where Astronaut is strongest.

Distribution: why Astronaut is everywhere

Astronaut’s real story is its reach. 100HP Gaming built its business on an aggregator-first model, distributing through large game hubs like SOFTSWISS and Timeless Tech. A single aggregator integration deploys a title across thousands of operators at once — which is how a game without a marquee marketing budget ends up in casino lobbies across a dozen markets simultaneously.

The trade-off is brand pull. Players search for “Aviator” by name; far fewer search for “Astronaut by 100HP.” Its growth is operator-push (it fills the lobby) rather than player-pull (players seek it out). That is a viable and clearly profitable strategy, but it positions Astronaut as a category filler rather than a category definer.

How Astronaut compares

vs. Aviator (Spribe): Aviator shares the same 97% RTP tier and curve mechanic, but adds a social layer — a live feed of other players’ bets and cash-outs — that drives its virality. Astronaut is the more solitary experience. If the social feed and brand recognition matter to you, Aviator leads; if you simply want the mechanic and it is what your operator carries, Astronaut delivers the same core game.

vs. Spaceman (Pragmatic Play): Despite the near-identical theme, Spaceman is a different game from a different studio, and its distinguishing feature is partial cashout — the ability to bank part of a bet while letting the rest ride. Astronaut does not offer that. Spaceman also carries Pragmatic Play’s broader tier-one licensing footprint.

vs. NexGenSpin titles: NexGenSpin games such as Capybara Crash and Crocodilo compete at the same RTP tier but lead with character-driven identity rather than a generic astronaut or plane — a deliberate move to stand out in a category crowded with interchangeable themes. Coverage varies by operator, as it does for most challenger studios.

Summary

Astronaut is a competent, conventional curve crash game whose strength is distribution, not innovation. Its ~97% RTP is category-standard, its provably fair system is credible, and its aggregator-first reach has made it one of the most widely played crash titles in emerging markets. It will not surprise anyone who has played Aviator — and that familiarity, paired with its lobby ubiquity, is precisely the point.

If Astronaut is the crash game in front of you, this is a fair, standard implementation of the format. Just verify the RTP in-game and set your cash-out target before the round, not during it.

Frequently Asked Questions

What is the Astronaut game?
Astronaut is a crash game developed by 100HP Gaming. An astronaut rises through space while a multiplier climbs from 1.00x. Players must cash out before the astronaut crashes; miss it and the bet is lost. It is distributed widely through game aggregators and available at many casinos in emerging markets.
What is the RTP of the Astronaut game?
Astronaut's commonly reported RTP is around 97%, which is the standard benchmark for curve crash games. RTP can vary by operator configuration, so check the in-game information panel before playing. A 97% RTP implies an expected loss of roughly $30 per $1,000 wagered over volume.
Who made the Astronaut crash game?
Astronaut was developed by 100HP Gaming, a studio that distributes through aggregators like SOFTSWISS and Timeless Tech. This aggregator-first strategy gives Astronaut broad reach across operators, particularly in India, Brazil, and other emerging crash-game markets.
Is Astronaut the same as Spaceman?
No. Both feature a space theme and are curve crash games, but they are made by different studios — Astronaut by 100HP Gaming, Spaceman by Pragmatic Play — and they are separate titles. Spaceman's distinguishing feature is partial cashout; Astronaut is a more conventional single-cashout crash game with wide aggregator distribution.
Is the Astronaut game provably fair?
Astronaut uses a provably fair system, meaning each round's crash point is generated from a cryptographic seed that can be verified after the round. This lets players confirm the result was not manipulated. Provably fair verification is standard across reputable crash games and is a key trust signal in markets where players actively check fairness.
