Comprehensive economic simulation showcasing market dynamics in a closed economy with 50 agents. Features real-time supply and demand curves, multiple economic scenarios (scarcity, abundance, tech boom, demand surge), market interventions (price floors/ceilings, taxes, subsidies), and a money printer mechanism. Watch producers, consumers, and traders interact through order books with detailed agent statistics, wealth inequality tracking, and exportable simulation data.

Comprehensive Social Security benefits calculator with break-even analysis. Input your earnings history to see monthly benefits at different retirement ages (62-70), compare lifetime totals with COLA adjustments, and analyze investment scenarios. Features detailed year-by-year projections, visual break-even point detection, and CSV export for financial planning.

Monte Carlo table-stakes experiment: equal starting stacks, dice decide each round, and the last stack wins. Compare fair play with a money-printer that recapitalizes Player 1 using newly created chips. Sweep bailout counts to map win rate, inequality, wealth share, and inflation with confidence intervals.
