In a single-elimination bracket, the best team is far from guaranteed to win — it must string together several wins, each a fresh chance to be upset. Simulating thousands of tournaments reveals the true championship odds for each seed. With little skill spread the field is wide open; with a big gap the top seed dominates, but even then rarely tops 50%.

About this simulation
The full Tournament Odds tool models a bowling roll with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
