Astronaut Crypto Crash Game
100HP Gaming, a Cyprus-based studio founded in 2022, built Astronaut and distributes it through Onlyplay. Released in 2025, it adds Green Crystal bonus signals, Red Crystal early-crash-risk indicators, and a Golden Shield loss-protection feature on top of a standard rising-multiplier curve. Published RTP sits around 97%, with a reported 10,000x ceiling, verified through HMAC-SHA256 provably fair cryptography.

A mathematical simulation of a $200 bankroll against Astronaut's published 97% RTP — not a record of real funded gameplay.
| Session | Bet | Rounds | Result |
|---|---|---|---|
| Conservative — 1.5x auto-cashout | $10 | 60 | +$0.00 |
| Moderate — 2.5x auto-cashout | $15 | 45 | +$187.50 |
| Aggressive — 6x auto-cashout | $10 | 30 | $-60.00 |
Total: +$127.50 (63.8% ROI)
Key findings
- • Modeled on Astronaut's published 97% RTP using the standard crash-point formula — the Crystal and Golden Shield features weren't modeled since their exact trigger mechanics aren't fully documented by 100HP Gaming. This is a simulation, not a funded playtest.
- • The moderate leg's above-average hit rate drove the entire session into simulated profit — a clear reminder that this result reflects one seeded run, not an expected outcome.
- • As a 2025-launched title, less independent long-run data exists on Astronaut compared to older titles on this list.
Challenges
- • The Green/Red Crystal signal system and Golden Shield feature add real gameplay complexity beyond a plain crash curve, which this simulation doesn't attempt to replicate exactly.
- • ETH gas costs on mainnet can matter more here than on Tron/BSC-based games — check whether the specific operator uses a layer-2 or off-chain balance system before assuming on-chain fees apply per bet.
A strongly positive simulated result driven almost entirely by one lucky leg — not something to read as evidence the game behaves favorably in general.
Multiplier Probability & Reported Extremes
1000x
100HP Gaming hasn't published a verifiable record-win archive for Astronaut. Reported maximum multiplier figures vary across sources, from the commonly cited 10,000x up to unconfirmed claims of 48,000x on some operator configurations. At 97% RTP, roughly 9.7% of rounds reach 10x and about 0.97% reach 100x regardless of which ceiling figure is accurate, since both thresholds sit well below any of the reported caps.
Community-reported, unverifiedWhy It's Unique
vs Spaceman
- ✓ Astronaut is provably fair via HMAC-SHA256; Spaceman relies on certified RNG without client-side verification.
- ✓ Astronaut's reported 10,000x ceiling is double Spaceman's hard 5,000x cap.
Special sauce
- 1. Green Crystal bonus signals and Red Crystal early-crash-risk indicators layered on the base curve.
- 2. Golden Shield feature offering a form of loss protection, distinct from a simple cashout mechanic.
- 3. HMAC-SHA256 provably fair verification, a stronger cryptographic construction than plain SHA-256 hashing.
Where Players Lose Money
Overreading Crystal signals as predictive
Scenario: Treating a Green Crystal appearance as a guarantee of a high multiplier round.
Why it fails: Without documented, verifiable trigger mechanics from 100HP Gaming, treating any in-game signal as reliably predictive is speculative.
Fix: Treat Crystal signals as cosmetic engagement features unless 100HP Gaming publishes their exact statistical basis.
Over-relying on Golden Shield as full protection
Scenario: Betting larger because Golden Shield is active, assuming it eliminates downside.
Why it fails: Loss-protection features typically offer partial, not full, protection — exact terms should be checked per operator.
Fix: Read the specific terms of Golden Shield before assuming it changes the fundamental risk of a bet.
No stop-loss on a newer, less-tracked title
Scenario: Applying the same confidence in long-run behavior as a game with years of community verification.
Why it fails: A 2025 launch means fewer independent data points exist on how Astronaut performs across many operators over time.
Fix: Start with smaller stakes until the title's behavior at a specific operator is better understood.
Assuming ETH gas fees don't matter for small bets
Scenario: Grinding sub-$5 stakes without checking whether the operator settles on-chain per transaction.
Why it fails: Mainnet Ethereum gas costs can exceed the value of very small bets if the operator doesn't use an off-chain balance system.
Fix: Confirm how the specific operator handles ETH transactions before committing to a micro-stake grinding session.
Chasing losses after a Red Crystal miss
Scenario: Increasing bet size specifically to 'make up for' a round flagged with early-crash risk that then busted.
Why it fails: Whatever the Red Crystal signal represents, the next round remains an independent draw from the same distribution.
Fix: Keep bet sizing flat regardless of in-game signal outcomes.

HMAC-SHA256 is a stronger construction than plain SHA-256 hashing, which is a genuine positive; as a newer studio and title, less independent long-run scrutiny exists compared to established names on this list.
