About Lawmaxxer
Learn game theory by losing in court.
Lawmaxxer is a free browser game about one of the most famous ideas in game theory: the Prisoner's Dilemma. You play a lawyer facing an unknown opposing counsel. Every round you both choose to Settle or Sue, and the case goes to whoever plays the long game better.
Why make a game about this?
The Prisoner's Dilemma explains a lot about the world: why rivals cooperate, why feuds escalate, why trust is hard to build and easy to lose. Most people meet it as a table in a textbook and forget it a week later. We think you learn it properly by playing it, getting burned, and working out why.
So every case in Lawmaxxer ends with a debrief. Win or lose, the court reveals who you were facing, how they decided their moves, and what would have beaten them. A loss is a lesson with a gavel attached.
