Inspection game

1. The inspector chooses check or skip while the other player chooses comply or violate. Choices are sealed until both respond. Roles are assigned randomly at the start of each game.
2. The inspector receives base minus inspection cost, or minus damage from an undetected violation. Fines do not become inspector income.
3. The actor receives base plus any violation gain, minus the fine if caught. Inspection catches a violation with certainty.
4. Cost must be below undetected damage and gain below the fine. Negative earnings are allowed. No violations means no detection-rate denominator, rather than zero percent.

All $ amounts are virtual game dollars.
