This Bingo Card Generator creates randomized, printable grids for events, educational activities, or remote work bonding (WFH). Unlike simple randomizers, this tool employs the Fisher-Yates Shuffle algorithm to ensure a mathematically uniform distribution of items across the grid.

When generating a standard 5×5 card, the center square is typically reserved as a Free Space. The probability of any specific item appearing in a specific cell (excluding the center) depends on the ratio of the pool size N to the available slots k.

To understand the uniqueness of a generated bingo card, we calculate the number of possible arrangements. If you have a list of n items and a grid with k empty slots (e.g., 24 slots for a 5x5 card with free space), the number of unique combinations is given by the binomial coefficient:

However, since position matters in Bingo (a line is formed by specific positions), the total permutations P are significantly higher:

Where:

• n = Total items in your input list.
• k = Number of slots on the board.
• ! = Factorial operator.
