You can solve the shape puzzle in Ao Oni by finding the missing die. The missing die is in the second floor of the old building.
the mean is the average; (9 +8+4 + X)/4 = 8; solve for X ; (21 +X)/4 = 8; X = 11
Form an equation and solve it
If I understand it correctly, that means you should solve the following equation: (5 + 9 + 12 + x) / 4 = 9
All rows, columns and diagonals must total the same number, which is the "magic number". You must enter the appropriate missing numbers to make this happen, using the number choices made available.
