The Guardian has published a 20-question quiz testing readers' knowledge of the finer details of the 2026 World Cup, which concluded after 48 teams contested 104 matches across 16 host cities in the United States, Mexico and Canada over 39 days. The quiz covers a wide range of tournament trivia, from goalscorers and records to statistics on penalties, assists and disciplinary incidents, offering fans a way to test how closely they followed the competition.

Questions range from who scored the tournament's first goal and which host city staged the most matches, to records such as Mohamed Hany's unwanted feat for Egypt and the number of England players sent off at World Cups following Jarell Quansah's red card. Other questions probe Spain's near-flawless defensive record, Lionel Messi's penalty-taking history, Argentina's late-goal habit, and oddities such as the latest goal ever scored in World Cup history, in the 125th minute, plus Wayne Rooney's verdict on the final's half-time show.
