This calculator estimates the most likely number of bingo cards in play according to the distribution of balls called and the number of winners. To use, just enter number of balls called, according to the letter, and the number of winners. Then click the type of game. The number of cards shown should be considered as a rough guess.
This calculator is not fully monkey-proofed. If you put in impossible or unreasonable input, don't expect to get a reasonable answer.
