Slot Summary

On November 12, 2024, CosmoX entered Onlyplay's lineup as a space-themed crash game with a 97% RTP and a lightweight file under 1MB. Each round turns on timing: the multiplier rises during the flight, and a cashout locks the displayed value before the run ends. Auto Bet and Auto X can automate the two repeated decisions without changing the generated result.
MechanicsCash out before the rising multiplier ends

How It Plays

A round starts after the betting countdown, then the displayed multiplier climbs until the flight ends. A successful Take action records the multiplier visible at that moment.

Auto Bet repeats the selected stake across rounds, while Auto X supplies a preset exit point. Manual cashout remains available before the ending event occurs.

Theme & Atmosphere

Space is more than surface decoration here because the rising flight provides a readable metaphor for escalating risk and an approaching end to each round.

The Futuristic and Science treatment stays deliberately light, supporting an interface that Onlyplay says occupies under 1MB and works across basic mobile hardware.

Bankroll survival simulator

How long could a bankroll last on CosmoX? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

Volatility tier: Mediumassumed — not published for this slot

Running simulation…
How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (97.00%), with wins capped at its top multiplier (10,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
