Spaceman vs other crash games
Spaceman vs other crash games is mostly a difference in what each publisher states: Spaceman’s Game Help gives a 95.50% RTP (the provider’s product page shows 95%) and a 5000x maximum multiplier, Spribe lists 97% RTP for Aviator, bustabit documents a 1% house edge and publishes its result formula, and SmartSoft’s JetX page states no RTP. All four run the same crash mechanic; where a figure is published, the house edge follows by arithmetic, and for JetX none can be verified from the provider’s information.
Key takeaways
- Spaceman’s Game Help states a 5000x maximum multiplier, and bustabit caps profit per bet at 1% of its bankroll. Spribe and SmartSoft publish no maximum multiplier.
- bustabit publishes its hash chain and result formula, and Spribe describes Aviator as provably fair. Neither source says anything about Spaceman.
- Pragmatic Play’s Crash Games page listed Spaceman alongside High Flyer and Big Bass Crash, as checked on 2 October 2026.
Spaceman vs other crash games: the published figures
Games like Spaceman, built on the same rising-multiplier mechanic, include Aviator, JetX and bustabit.
| Game | Publisher and first date | Published RTP or house edge | Maximum multiplier |
|---|---|---|---|
| Spaceman | Pragmatic Play; announced on 24 March 2022 | 95.50% RTP in the Game Help, version 1.7; 95% on the provider’s product page, as checked on 2 October 2026 | 5000x (Game Help) |
| Aviator | Spribe; live in January 2019 according to Spribe | 97% RTP on Spribe’s Aviator page | Not published by the provider |
| JetX | SmartSoft Gaming; launched in 2018 according to SmartSoft | Not published by the provider | Not published by the provider |
| bustabit | No separate provider; first announced on 25 July 2014, originally on moneypot.com | 1% house edge (bustabit’s documentation) | Technical limit of about 4.46 quadrillion x; profit per bet capped at 1% of the bankroll |
RTP (return to player) and house edge are two views of one number, so bustabit’s 1% edge corresponds to a 99% return. Spaceman’s two figures are set out with their sources on the page about Spaceman’s RTP.
| Game | Fairness documentation | Notable mechanic |
|---|---|---|
| Spaceman | An RNG (random number generator) title, in the provider’s words; its March 2022 release referred to provably fair mechanics, and the Game Help’s description of them was removed in July 2024 | 50% cashout on a single bet; reaching 5000x pays out automatically |
| Aviator | Provably fair, in Spribe’s words | A second bet panel (Aviator’s in-game rules) |
| JetX | Not covered by the sources reviewed for this site | Described by SmartSoft as the first “flying” crash game (the vendor’s claim) |
| bustabit | Described by bustabit as provably fair: a published hash chain, a salt taken from a Bitcoin block and a published result formula | Published odds for every target; about 1 round in 50 ends instantly at 1.00x |
For Spaceman, the dated record behind that cell is on the page about whether Spaceman is fair, and the information inside the game is the place to check.
The crash games overview sets out which parts of the format are fixed and which vary.
What is published about the other three games
bustabit. Generally accepted as the first crash game, it opens the history of crash games. It also publishes more of its internals than the other three: the chance of winning at target t is 99 ÷ t percent, and the formula that converts a hash into a multiplier is public. That formula belongs to bustabit only, not to Spaceman or Aviator, and the hash chain behind it is explained on the page about provably fair crash games.
Aviator. Its bet structure, seed scheme and published figures are set against Spaceman’s in full on Spaceman vs Aviator.
JetX. SmartSoft’s page gives a launch year and the vendor’s “first flying crash game” claim but no RTP, so no RTP, house edge or expected value for JetX can be verified from provider-published information.
The same target in three games
One way to see what a published return figure does is to hold the cashout target fixed and change the game. The odds for bustabit are published: a 2.00x target wins 49.5% of the time.
Neither Spribe nor Pragmatic Play publishes a multiplier distribution. Under the multiplier model, in which the chance of reaching a target is roughly the RTP divided by the target, a 2.00x target would be reached about 48.5% of the time at an assumed RTP of 97%, the figure Spribe lists for Aviator, and 47.75% of the time at an assumed RTP of 95.5%, the figure in Spaceman’s Game Help. Those two figures are our calculation from a model, not the providers’ internals.
The three figures sit within two percentage points of each other, and under the model the expected return at every target equals the RTP, which is below 100% in each case. JetX is left out because its provider’s page states no RTP to calculate from.
Pragmatic Play’s own crash lineup
Spaceman is not the provider’s only crash title. As checked on 2 October 2026, Pragmatic Play’s Crash Games page listed Spaceman alongside High Flyer and Big Bass Crash.
The same page calls Spaceman the provider’s original crash game and credits it with introducing the 50% cashout feature. That is the provider’s wording. Spaceman was announced in March 2022 in a release that described it as Pragmatic Play’s first crash-style game.
This site covers Spaceman only, and no figures are given for the other two titles.
