About CosmoX
CosmoX is an Onlyplay crash game with a space-rocket theme. A rocket flies away and the multiplier goes with it.
CosmoX is made by Onlyplay.
How a round works
Two bet panels run side by side. Cash out each bet before the rocket is gone.
How to play the CosmoX demo
- Press Play demo. The official demo opens in the window above; some take a few seconds to connect.
- Use the controls inside the game to set a demo stake.
- Start a round and follow what happens on screen.
- Cash out or collect whenever the game lets you, then start another round.
Worth trying: Keep one bet on a low target and the other on a higher one, and watch which of them survives more rounds.
Demo credits are virtual and have no cash value. Results in a demo do not predict results anywhere else.
