DoUKnowBall is a free sports trivia playground. Over 100 games covering soccer, pro football, basketball, baseball, hockey, college sports, Formula 1, tennis, golf, NASCAR, and combat sports. Some are quick daily puzzles you can knock out on the bus. Others are full career and manager sims you can sink a whole evening into. Everything runs right in your browser, no download and no signup required.
DoUKnowBall started in early 2026 as a handful of soccer guessing games built by one fan who was tired of trivia sites that ask you a single question and call it a day. Players kept showing up, so the games kept coming. A few months later the site covers eleven sports, with fresh puzzles dropping every single day and new games shipping constantly.
Getting the data right comes first. Real rosters, real stats, verified lineups. When a grid says a player suited up for two clubs, he actually did. If something looks wrong anyway, every page has a Report a bug button in the footer that lands straight in our inbox with the page attached, and we fix it.
Second, games have to be worth coming back to. That is why the dailies have streaks and share cards, the grids score you on how rare your answers are, and the sims have real depth: contracts, trades, injuries, playoff runs, whole careers. No two-second gimmicks.
A quick tour: daily puzzles like the grids, Connections, Higher or Lower, and the guess-the-player games. Deep sims like Soccer Career, My Career modes for the four big American leagues, Front Office GM sims, CFB and CBB Dynasty, and Club Manager. Game-show formats like Sports Millionaire and Minefield. And the Conquest imperialism maps, where one team ends up ruling the whole country. If you know ball, something here will humble you.
