The site cosmobit.org looks unfinished, registration page reloads cyclically. Difficult switch to Game description, below is the content of this page:

How it works

Getting started:
Each new member starts the game with a new spaceship costing 100 satoshi, with a planet, with 100 satoshi at his balance and with 3 free portals. Any player can get a second planet for free by clicking on a transparent planet labeled +++Planet+++. Each player receives extra 100 satoshi after registration. Entering the CosmoBit.org for the first time the player begins his first flight.
When starting new flight the server generates a number from 1 to 5 using the provably fair system. This is the number of maximum asteroids that the spaceship can attack in one flight.

Asteroids and ships:
There are 7 types of asteroids highlighted by rarity. Asteroid rarity corresponds to spaceship rarity. The rarer the asteroid, the greater the reward. Each new spaceship has 10 shots. It turns out that each shot is worth a tenth of the price of the spaceship. During each flight the ship can attack one of the three asteroids: a small one, a medium one and a large one. Player chooses one of them to attack.
Each asteroid has a different reward and probability of winning.

Formula:
Chance to win = Asteroid return / Rate multiplier
Asteroid return is 110% for small asteroid, 100% for medium one and 90% for big one.
Rate multiplier for small asteroid ranges between 1.2 to 1.4.
Rate multiplier for medium asteroid ranges between 1.5 to 4.5.
Rate multiplier for big asteroid ranges between 5 to 10.
Turns out that the smaller asteroid is than the higher is return and chance to win, but the smaller is the winning. The bigger asteroid is than the smaller is return and chance to win, but winnings ate bigger.

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%
