Then, when you click on any of the options (numbers) in any of the boxes, all the options that stop being possible are taken out of the matrix. Pretty soon, you should end up with a solved sudoku.
The programming shouldn’t be that hard and, in fact, should be quite similar to the stuff I did for the poetrymatrix, which I worked on late last year. So, today I wanted to start working on this one and checked what was already out there. Well, if you search for it, you’ll notice, like me, that, really, the world doesn’t need another sudoku solver.
