How to Play Astronaut
The goal is to collect before the rocket jets off screen. The multiplier rises for as long as the flight lasts, and the crash point is fixed before the round starts. The steps below cover a full round.
-
Configure your bet settings
Bets run from 0.10 to 150 per panel. Two settings are worth fixing before the round:
- Auto cash out - an optional target up to ×999 that collects on its own.
- Betting panels - one panel for a single bet, or both for two independent bets on the same round.
-
Place your bet
The stake has to be confirmed before the pre-round countdown ends to join that round.
-
Watch the launch
The rocket flies up into the screen and the multiplier rises continuously from ×1.00 as it climbs.
-
Cash out before it jets away
Collect manually at any point, or let the auto cash out target do it. The stake is multiplied by the value showing at that instant and credited.
-
Win or lose
- Collected in time - the win is credited immediately.
- The rocket jets away first - the round ends and any uncollected bet is lost.
Each panel settles on its own, so one can collect early while the other keeps running.

Astronaut FAQ
What is Astronaut?
Astronaut is a crash game from 100HP Gaming. A rocket launches and a multiplier rises with its flight, settling your bet at whatever value you collect on. If the rocket jets off screen first, the bet is lost. It is built deliberately small so it runs on weak hardware and slow connections.
Can I play Astronaut for free?
Yes. The demo runs on play money with no registration or download, at the same 98% RTP and ×50,000 ceiling as the real-money version.
Why is Astronaut built so small?
At roughly 1.6MB it loads where heavier crash games stall — 100HP claims it works on 2G. Timing is the whole game in this format, so a build that stays responsive on a slow phone is a functional advantage rather than just a convenience. The animation can also be turned off to reduce the load further. The maths is unaffected.
Why does auto cash out stop at ×999 when the ceiling is ×50,000?
The two are separate limits. ×50,000 is the highest multiplier a round can reach; ×999 is the highest target the automatic collect will accept. Anything above that has to be taken by hand, which in practice means watching the round rather than leaving it to run.
Is Astronaut a reskin of another 100HP game?
Yes. 100HP runs several titles on this engine, Meta Crash among them, sharing 98% RTP to a ×50,000 ceiling with stakes from 0.10 to 150, the same dual panel, the same ×999 auto cash out limit and the same chat and leaderboards. Astronaut is the stripped-back one, built at around 1.6MB where the others carry heavier artwork.
