What Spaceman and Aviator have in common

• The crash mechanic. In Spaceman the multiplier rises to a random, predetermined value, and any amount not cashed out by then is lost, according to the Game Help. Spribe describes Aviator as an increasing curve that can crash at any time.
• A shared round. Pragmatic Play’s launch release described Spaceman as a social, multiplayer RNG title, and Spribe describes Aviator as a social multiplayer game. In crash games generally, each player still bets against the house, not against the other players in the round.
• No skill edge. The Spaceman Game Help states that it is not a game of skill: the player’s choice has no impact other than deciding when to cash out. Under the model explained on the multiplier page, the expected return of a crash game is the same at every cashout target.

Both games belong to a format generally traced back to bustabit in 2014, and the dated timeline of the genre sets out the sequence.

Difference one: two bets or one bet with a 50% cashout

Aviator’s in-game rules describe a second bet panel, so two bets can be placed at once. The Spaceman Game Help describes a single bet per round and no second bet panel. In its place Spaceman has CASHOUT 50%, a feature that Pragmatic Play’s Crash Games page, as checked on 2 October 2026, credits Spaceman with introducing. That is the provider’s own claim.

According to the Game Help, CASHOUT 50% secures the win on half of the bet; the other half stays in play and is lost unless it is cashed out before the round ends. The full mechanics are on the page about the 50% cashout.

The two arrangements can produce the same totals. A 10-unit Spaceman bet with CASHOUT 50% at 2.00x and CASHOUT at 4.00x returns 10 units from the first half and 20 from the second. Two separate 5-unit bets cashed out at 2.00x and 4.00x return the same 30, and if the round ends between those two multipliers, either arrangement returns 10.

What differs is the form. Spaceman fixes the split at half of one accepted bet, while Aviator’s in-game rules describe two bets placed through separate panels. How each Aviator bet is settled is a matter for that game’s own rules.

Difference two: how fairness is documented

Aviator. Spribe describes Aviator as provably fair. According to Spribe, a hash of the next round’s server seed is visible before the round, and that seed is combined with client seeds from players to derive a result that can be checked from the game history. Spribe does not publish a formula that turns the hash into a multiplier.

Spaceman. The March 2022 press release referred to provably fair mechanics, and the change log of Game Help version 1.7 records that their description was removed on 10 July 2024. The document does not say whether the in-game check itself was removed or only its description, so the information inside the game is the place to check. The dated record is on the Spaceman fairness page.

A provably fair check shows that a round’s result was not altered after it was committed to, not what the game’s RTP or house edge is. The method is explained on the page about provably fair schemes in crash games.

Difference three: the gap in published RTP

Spribe lists 97% for Aviator. Both figures that Pragmatic Play publishes for Spaceman are lower, and the sources behind each figure are set out on their own page.

As arithmetic, 97% implies a house edge of 3%, and the 95.50% in Spaceman’s Game Help implies 4.50%. Over 1,000 units staked, that is a long-run average return of 970 units against 955. Both are averages across a very large number of rounds, not a forecast for a session, and both are below the amount staked.

What this comparison leaves open

• Aviator’s maximum multiplier. Spribe publishes none, so none is given here. Spaceman’s 5000x comes with a maximum payout of 4,999:1 or the currency equivalent of €500,000, whichever is reached first, according to the Game Help.
• Operator-set values. Spaceman’s bet limits depend on the operator and currency, and operators may apply their own lower payout caps. For either game, the information screen inside the game is the authority.
• Which game to choose. No figure here is a recommendation of either game.
