Hacker Factor
The Game of Oligarchy
This is an automated implementation of Brewster Kahle's "Game of Oligarchy".The basic premise: demonstrate that in a free market, only one person ends up rich, and the others broke.
The rules:
- All players begin with $100.
- The socialism expansion is currently disabled. Click here to enable it and see the difference.
- In each round, players randomly pair off. If there are an odd number of players, then one player sits out during the round.
- For each pairing:
- Both players bet half of the lowest $amount between the two players. E.g., if one player has $50 and the other player has $75, then they both bet $25 (half of $50). No fractions, round up to the nearest $1.
- They agree on a coin flip. The winner gets the amount that was bet from the loser.
- When a player has $0, they are out.
- The game ends when there is only one player left (the winner).

Game over after 125 rounds. Player 5 won.
For fun, I also created a new rule for socialism expansion that adds stability to the game. (As Brewster put it, "2% is a small price to pay for stability.")
