Spaceman by Pragmatic Play: How It Works & RTP
Spaceman by Pragmatic Play is a crash-style game with a 95% RTP, where a floating astronaut rises, a multiplier climbs, and you must cash out before he flies off-screen. Miss the exit and you lose that bet.
How a round works
You place a bet before the round starts. The spaceman then ascends and the multiplier rises from 1.00x. At a random moment the spaceman flies away and the round ends. If you pressed cash out before that, your stake is multiplied by the value shown at the instant you exited. If you waited too long, the bet is lost. Timing your exit is the only decision the game asks of you.
The two-bet option
Like other crash titles, Spaceman lets you run two bets in the same round. A common pattern is to cash one out early to bank a small return, then let the second ride for a larger but less likely multiplier. This does not change the underlying math, it simply spreads your stake across a safer and a riskier exit. The house edge still applies to every bet you place.
What the 95% RTP means
An RTP of 95% means a 5% house edge: over a very large number of rounds, the game is built to return about 95% of total wagers. This is a long-run statistical average, not a promise for any session. Short stretches can swing far above or below it in either direction.
The odds of reaching a multiplier
For crash games the probability of a round reaching a multiplier m is approximately RTP divided by m. With Spaceman’s 95%, that gives the estimates in the table below. Notice how quickly the chance drops as the target multiplier rises, which is exactly why high-multiplier targets are the riskiest play.
| Target multiplier | Approx. chance of reaching it (0.95 / m) |
|---|---|
| 2x | ≈ 47.5% |
| 5x | ≈ 19.0% |
| 10x | ≈ 9.5% |
| 20x | ≈ 4.75% |
Certified RNG, not seed-based provably fair
Spaceman uses a certified random number generator. That differs from the seed-based “provably fair” model used by some other crash games, where players can personally verify a specific round using a server seed, client seed and nonce. With certified RNG, fairness rests on independent laboratory testing of the system rather than per-round player verification. Both are legitimate; they simply offer different kinds of assurance.
How it compares to Aviator
Spaceman’s closest cousin is Aviator, which runs a slightly higher 97% RTP and uses the provably-fair model. The gameplay is near-identical: cash out before the crash, with a two-bet option. If RTP is your priority, see our Aviator RTP guide; for a variable-RTP alternative, our JetX RTP guide explains how that game’s return changes by operator.

Correction, 26 July 2026. This page previously gave Spaceman’s RTP as 96.50% and derived its probabilities from that figure. Pragmatic Play’s own game page states 95%. The figure and every number computed from it have been corrected. The 96.50% we published is widely repeated elsewhere and may reflect an earlier or alternative certified build; we publish the studio’s current stated figure and say so.

P(reach m) = RTP / mEvery multiplier probability on this page is computed exactly from the crash-curve identity P(reach m) = RTP divided by m. For a 97% RTP build that gives P(2x) = 0.485 and P(100x) = 0.0097. No sampling, no estimation: the identity is exact, and it is why expected value equals RTP at every cash-out target.
