About DoUKnowBall

What this site is

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.

How it started

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.

Who makes this

One person. DoUKnowBall is an independent project built and run by a lifelong sports fan, not a media company and not a league. The same person writes the game engines, checks the rosters, bakes the daily puzzles and reads every bug report. The games are free, there is no account wall, and the only way the site pays for itself is the ads, which is why it will never be buried in them. If you want to talk to the person behind it, douknowball1@gmail.com goes straight to him.

What we care about

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.

The games

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.

A note from the maker

Hey, thanks for checking out my site. DoUKnowBall is my first ever coding project, an independent site I build in my free time. I'm constantly working on it, fact checking everything and adding new games, so if something looks off, tell me with the Report a bug button at the bottom of any page and I'll get on it. Have a blessed day.
