Hexa Do "Hexa do" is a Sudoko modification. Instead of 3x3 cells in sudoku it is used 4x4 cells in "Hexa do". Since there is 16 cells vertical and horizontal and in the box. We need to use a number system which goes from 1 to 16.we use numbers from 1 to 9 to represent one to nine. But from 10 we starts to use alphabet. A for 10, b for 11 and etc. (16 is represented by g which is the last sign in this system.
