Spread (WIP)

Custom

Custom bet types are built through the console input when placing a bet that doesn't match the options above.

• Selection (selections <= total)
• Ordering (If a bet outcome is based on ordering of selections)
• Flexible (Should this bet be a flexible bet eg. Exacta -> Show)
• Event Count (Number of independent events this occurs over)

Config, Probability, Odds and Randomisation

Configuration

The simulation was built with repeatability, predictability and similarity to real-life in mind.

There are a number of configurable options:

• Complete randomisation (Initial seed is optional)
• Randomisation of outcomes based on a tuned parameters for a distribution (eg. normal, beta, gamma)

Probability Calculation

Where:

n = outcomes
r = selections

Combinations (Non-ordered selections):

eg. Trio (Pick 3 in any order)

n! / r!(n-r)!

Permuations (Ordering selections):

eg. Trifecta (Pick 3 in order)

n! / (n-r)!
