About

Washington Pinball Predictions is an imaginary-money betting game for the Washington State championship tournaments.

Odds were calculated using simulations based on Glicko player ratings from Matchplay.Events.

Unlike in a real sports book, these odds will not be updated in response to bets being made.

To the see the code used to calculate the probabilities, visit this Github project: pinball-state-champs-sim.

To see the raw probabilities that were used to compute the odds, view this Google spreadsheet.

The odds are only as accurate the Glicko ratings used to compute them. Also, the Glicko ratings were generated under conditions much different than what will be found in the state finals. The state finals machines are setup to be extra difficult.

Any player could pull an upset and win on any given day. Do not rely on these odds for anything other than entertainment.

This site was created by John Garnett with a little help from Claude Code. Claude helped mostly with the UI. It did not help with the simulation code.
