Im finding their FAQ or any info but you cant see it since the game do directly starts and as i observed this acts as a faucet site earning some satoshis on hitting those
asteroids when i tend to make some upgrades you can see the links about the game
http://cosmobit.org/about.php and i say this is an another dice/multiplier game.
Do these multipliers realistic?
Examples::
For the examples below, a ship that costs 1 Bitcoin will be used. Hence one shot from this ship costs 0.1 bitcoin.
Small asteroid has return 110% and rate multiplier 1.2:
Chance to win = 110% / 1.2 = 91.67%
In this example, the player wins 0.12 BTC with a probability of 91.67%
Medium asteroid has return 100% and rate multiplier 4:
Chance to win = 100% / 4 = 25%
In this example, the player wins 0.4 BTC with a probability of 25%
Big asteroid has return 90% and rate multiplier 10:
Chance to win = 90% / 10 = 9%
In this example, the player wins 1 BTC with a probability of 9%
