### Chance and Multiplier

Dice is a game where you roll over (or equal to) or under (or equal to) a number to win. Chance is chosen by the player (0.01%-98%). The multiplier is set so the return is always 0.99 compared to the win chance. Through a simple formula (with `Chance`

ranging from 0.1 to 95) the multiplier for every chance input from the player can be calculated.

The available multipliers can be found in the Dice contract where `10421`

stands for the 1.0421x multiplier and `9900000`

for the 990x multiplier:

Here are some examples of specific outcomes:

### House Edge

The 1% house edge is taken when the win chance is being calculated, because `99000000000`

is always being divided by the multiplier:

When we take the 2x multiplier as an example, `99000000000/20000=4950000`

leads to a 49.5% win chance. This is a 1% house edge (`50.5-49.5`

). On a win or loss the average return is always 0.99.

### Odds
