In the 75 ball game, it would be nice to have the corresponding letter of the B I N G O card for each number. "B" for 1 to 15; "I" for 16 to 30; "N" for 31 to 45; "G" for 46 to 60 and "O" for 61 to 75. The overall board is superb, showing which numbers have been called in yellow and the last number in red. This board can be arranged in 5 lines (B I N G O)
