Welcome to Sudoku, the classic number logic game! HOW TO PLAY: A board with only 1 solution will be generated. This board is a 9x9 grid. It is split into 9 rows, 9 columns, and nine 3x3 boxes. Cells that are already dark cannot be changed, but cells that are lighter can. Press a key on your computer, from 1-9, or click one of the buttons on the side to input that number into that cell. Typing 0 or clicking “Clear Cell” will clear the cell. The objective is to fill in the grid to ensure that no number, from 1-9, appears more than once in a row, column, or 3x3 box. When you fill in the puzzle, the game will inform you whether you have correctly solved the puzzle or not. Good luck! NOTE: Paste your save codes here: https://scratch.mit.edu/discuss/topic/884268/
