75-Ball Bingo
The standard format in the Philippines. A 5×5 grid with 25 squares — 24 numbers and one free centre space. Numbers are drawn from 1 to 75 and assigned to specific columns: B (1–15), I (16–30), N (31–45), G (46–60), O (61–75). The free space in the middle always counts as called. Winning patterns vary from simple lines to complex shapes and full-card blackouts depending on the active room.
