Fictional rules: 1,000 one-number tickets at 1 credit, five numbers from 90, gross payout includes stake. Concentrated tickets share one number; the rest spread as evenly as possible. Simulate 1,000 treasuries, stopping each below zero. Lines show 10th percentile, median and 90th percentile; these are outcomes, not confidence bands. No taxes, costs or historical payout schedule are modelled.

The story behind it

Stephen Stigler’s history connects Casanova with the French lottery of the 1750s. The state faced variable liabilities shaped by players’ choices. Our fictional treasury explores that problem: a positive average return does not supply the cash needed on every night.
