This program creates solved sudokus in less than a tenth of a second! This project could be seem difficult, but once you've understood the method everithing gets simpler. I've used a new method: it works like a solving sudoku script, but instead of going in order, adds a casual number that can fit (watch the video in credits for better understanding)
Thanks sooooo much to @Dinosu for his great explanation video of how a computer can solve a sudoku, in wich I did some changes (all code is mine though) https://scratch.mit.edu/discuss/youtube/Q9IDGfrlFHc tags: #sudoku #sudoku%20generator #generator #fun #fast #creator #sudoku%20creator #speed #solved %20sudoku
