head-side-gearThe mathematics of Mafia

Author: Vitaly - mr. Koteo (Brisbane Mafia Club)

Sports Mafia is not just a social game β€” it is a system of probability, structure, and decisions under uncertainty.

This part teaches you how to move from:

  • β€œWho feels Dark?” to

  • β€œWhich worlds are possible β€” and which decision is best across them?”


Core Idea

You are not solving the game. You are reducing possibilities.

Every action:

  • vote

  • check

  • kill

  • hesitation

creates constraints that eliminate worlds and shape the outcome.


How the Game Is Won

  • Red wins by convergence β€” reducing uncertainty fast

  • Dark wins by delay β€” preserving ambiguity

Critical rounds (8, 7, 6, 5) are where structure matters more than reads.


Key Concept: Expected Value (EV)

The goal is not to be right once.

The goal is:

make the decision that gives the highest chance to win across all possible worlds

A correct decision can lose. An incorrect one can win. Over time, only EV-positive play is consistent.


What You Will Learn

  • how probability works in real games

  • how votes create structure

  • how to recognise critical positions and parity

  • how to make decisions under uncertainty


How to Use This Part

Use it to:

  • analyse games correctly

  • stay logical under pressure

  • choose the best available decision, not the most convincing story


Bottom Line

Mafia is not about guessing the truth.

It is about:

making the best decision before the truth is known.
