Fill in all the missing numbers on the wooden sudoku board. Look carefully at the numbers already given at the start of the game. Using the knowledge that the numbers 1 through 9 may only occur once in every row, column, and block of 9 cells, you should be able to figure out where all the other numbers ought to go by a process of elimination. This will take quite a bit of patience though. Look carefully and try to solve all these fun sudoku puzzles
