Bingo is a chance-based board game that uses a drum with numbered balls and cards with random combinations. Its origin is traditionally placed in the 16th century, although there are various theories about its evolution. It is a limited decision system where the main interaction consists of marking numbers announced by a caller until completing a line or card. Its global popularity makes it a reference for low-mechanical-complexity social gaming, with two main varieties of 90 and 75 balls that define its structure and gameplay rhythm in different regions.
