This is a Sudoku game that I wrote in JavaScript, since I didn't really like most of the web-based Sudoku games I found. It can generate boards of varying difficulty, or you may input a board of your own. You may play the actual game on my site at <a href="https://parkscomputing.com/page/sudoku" rel="nofollow">https://parkscomputing.com/page/sudoku</a>
