Today Becky finished her first sudoku puzzle in about 30 minutes. Sudoku is a number puzzle made up a 3x3 grid of 3x3 grids making a large 9x9 grid. The grid is partially filled in with numbers 1-9 and the goal is to complete the puzzle so that each row, column, and 3x3 grid uses each digit once. There's only one solution and she found it, with some helpful proof-checking from Alex.
