In Lucky Bingo each round begins by purchasing a card. Each card has a 5×5 grid of 25 squares — the centre square is usually a "Free Space" that is filled automatically. Each column covers a specific number range: B covers 1–15, I covers 16–30, N covers 31–45, G covers 46–60 and O covers 61–75 — numbers are drawn from a total pool of 75.
Once the draw starts, the system randomly draws balls one by one and announces the numbers. If a drawn number appears on your card, that square is marked automatically. In JILI Lucky Bingo this draw process is presented through animated graphics, so every ball draw is clearly visible.
You also have the option to buy more than one card in the same round. Holding multiple cards increases your chances of winning, but each card requires a separate bet.
