Football Bingo is a free daily football game in which nine squares each state a fact — a club, a league, a nationality, a position, a footedness, a cap count, a trophy, a treble or a big transfer fee — and players arrive one at a time for you to place or let go. A player can only go in a square they genuinely satisfy, it is one player per square, and a placed player is gone. Skips are free and unlimited, which sounds generous until you notice the stream of players is finite: that, and not your patience, is the real budget. A wrong square costs nothing but the count, and the same player stays in front of you until you deal with them. New card daily at midnight UTC.
By putting the player currently on screen into a square whose fact they satisfy. There is no partial credit and no reordering afterwards — one player per square, and once they are placed they cannot be moved to a better square later. That is the whole tension of the game: a player who fits three squares can only ever fill one.
Nothing directly. Skips are free and there is no limit on them, because declining to claim something you are unsure of is exactly the action the game wants to feel safe. What it does cost is a player out of a finite stream, so a card left half empty at the end is usually a card that was too fussy early on.
Clubs, leagues, nationalities, positions, which foot a player uses, cap counts, trophies won, trebles and large transfer fees. Every square is a claim that can be graded against the dataset, and the grading is fixed when the card is generated, so the same square always accepts the same players for everybody.
The card closes with whatever you filled. Giving up early does the same thing and reveals a single player who satisfies every square you left empty, which is often a more instructive answer than nine separate ones. Either way the game is done for the day.
Place a versatile player in the narrowest square they fit, not the first one you notice — the broad squares will be filled by someone else later, the narrow ones probably will not.
Footy Grid poses the same fit-the-constraint question with the players left to you, and Connections hides the trait instead of printing it.
