The Replay Cup

A what-if simulator for the 2026 World Cup knockouts. All 16 real matches are replayable with your own lineups, formations and instructions on a possession-level engine: team strength fitted on 4,000+ real internationals, every kick-off replayed 1,000 times in a background worker, and a live 3D pitch. A full “how it works” page shows every formula and constant.

A quick card game about building a startup. Twelve months, five stats, up to three moves a month; events force a decision, combos reward focus, and your user count decides the ending. Balanced with a headless simulator that plays thousands of runs, and smoke-tested end-to-end with Playwright.
