World Cup-dle (JLA Tactics Board)

Each World Cup-dle puzzle hides a national team's starting eleven from one World Cup match. You are told the stage of the tournament, the opponent and the formation, and you guess a national team and a year, with five guesses in all.

After a guess, the pitch lights up. A position turns green when a player in your guessed lineup played at the same club as the hidden player at the same time, and yellow when they played for the same club in different years. Either way the club badge appears in that spot, so the pitch fills with Chelsea, Tottenham or Manchester City crests that point you to the right squad and era.

Puzzles are numbered and dated, and there is a daily leaderboard. Today's and yesterday's puzzles are open to everyone with no sign-up; a free account unlocks the full archive and your stats. The page has no ads. The game is made by the team behind the JLA Tactics Board, a football tactics app founded by YouTuber James Allcott, which also runs Prem-dle and Champs-dle.

The game page is translated into ten languages besides English, among them Spanish, Portuguese, French, German, Italian and Japanese. It plays the same on a phone, where the pitch fills the screen and the guess box sits just below it. It suits football fans who remember squads and transfers across decades of World Cups.
