- The center square is marked "Free" and is automatically considered marked for any bingo line that passes through it.
- To achieve a bingo, you need to mark five squares in a row: horizontally, vertically, or diagonally.
- The center "Free" square can be part of a horizontal, vertical, or diagonal line to complete a bingo.
- For example, marking the entire third row (5, 22, Free, 32, 1) would be a horizontal bingo.
- Similarly, marking the entire middle column (20, 25, Free, 15, 31) would be a vertical bingo.
- Marking the diagonal from top-left to bottom-right (8, 7, Free, 12, 16) or top-right to bottom-left (6, 14, Free, 8, 25) would also be a bingo.
- Any other combination of five consecutive marked squares in a row, column, or diagonal, including the "Free" space, counts as a bingo.
