Up to 20 cards per batch with the cards slider. Each card is independently generated with fresh random draws, numbered for tracking, and every number within a card is unique — no repeats, exactly like a real bingo card set.

In classic 75-ball mode each column follows the US standard: B draws from 1-15, I from 16-30, N from 31-45, G from 46-60, and O from 61-75, with a FREE space in the center of 5×5 cards. Custom mode draws every number from a single range you choose (1 to your maximum), which is handy for classroom or picture bingo variants.
