• This is a variant of sudoku that I adapted for the multiple choice format. Instead of solving the whole puzzle, you are only required to solve the value of X in each puzzle.

    Sudoku is a type of puzzle which typically uses numbers, but it isn't really a "math puzzle".  There is a 9x9 grid, as illustrated above.  Some numbers are given to you. The objective is to figure out the missing numbers based on the following rules:

     

    1) Each row contains 1 to 9 once and only once.

    2) Each column contains 1 to 9 once and only once.

    3) Each box, demarcated by the heavier line, contains 1 to 9 once and only once.

     

    All puzzles can be solved by pure deduction, without guessing.
