Yes. Each game picks 10 years at random from the chosen competition's full historical dataset. Every game is different.

Every champion and runner-up pairing has been triple-verified for accuracy across multiple sources. If you spot an error, please contact us at hello@whowonthatyear.com and we'll fix it.

The timer is what makes it a game rather than a search exercise. Ten seconds is enough time to think but not enough to look it up. If the timer runs out, the round is marked as a miss and the game moves on.

At launch: Formula 1 (Drivers Championship, Constructors Championship), Tennis (Wimbledon, US Open, French Open, Australian Open — Men's and Women's), Football (FIFA World Cup, Champions League, Premier League, La Liga), and Cricket (IPL Champions, IPL Orange Cap, IPL Purple Cap). More sports are coming soon.

The Daily Challenge is coming in v2. It will give every player the same set of questions each day, with streaks and leaderboards. Stay tuned.

Email us at hello@whowonthatyear.com with the competition, year, and what you believe the correct answer to be. We verify all reports and fix errors promptly.

Cricket, NBA, Golf, and Rugby are on the roadmap. No firm dates yet, but we're building them.
