Bingo Card Logic Puzzle Walk-through 7
Column N, row 5 tells us only 8 boxes were marked off. You can count the ones we have already placed from the list in Column B, row 4--2, 41, 37, 63, 67, and Free--or you can note that the the little icons for the marked-off squares are Xed out boxes, and just count those! Either way, that tells us that the two remaining marks must be in the Bingo, or Chris wouldn't have won. But we also know that the number 17 has to appear on the card, because all the numbers whose ones digit is 7 appear (column B, row 1). So 17 must be in column I, row 2. Then column B, row 2 tells us that the Bingo has two even numbers. The only possible Bingo numbers for column G, row 2 are 55 and 56, so column G, row 2 must be 56.
