A free daily sports trivia game.
Every sports argument eventually turns into the same question: do you actually know ball, or do you just know the famous names? Ball Knowledge is built to settle it. Each prompt has a whole list of right answers, and the game scores you on how few other players found the one you gave.
Naming the obvious superstar keeps you alive. Naming the role player, the forgotten champion or the one-season wonder is what wins the day.
There are around 300 prompts, covering championships, awards, draft classes, records, Olympic history, the origins of leagues and clubs, and the rules and vocabulary of each sport. See How to play for the full rules.
A trivia game where you can be marked wrong for a correct answer isn't worth playing, so every answer list aims to be complete. Lists come from official league and federation records, the Olympic results database and standard sports references, and each one notes the date it was checked. Questions about history are fixed lists that never change. Questions about active players or current records name a cut-off date, or are refreshed weekly from season stats.
Rarity is set by players. Each prompt starts with an estimate of how often fans would give each answer, then re-ranks every night from real answers, so the scoring reflects what fans actually know.
The game is free and supported by ads. Ads never appear during a question or an online game. You can play without an account; signing in with Google only saves your streak and puts you on the leaderboards under a nickname. We don't sell your data. The privacy page lists exactly what is kept.
