"If you are not familiar with Sudoku it is a logic placement puzzle. It is normally presented in a 9×9 grid but the puzzle above is a smaller easier version.

The objective is to fill the grid so that each column, each row, and each of the six 2x3 boxes contains the digits from 1 to 6. Some of the numbers have already been placed ln the grid."
