This is an ultimate Sudoku generator. Press Green Flag. Use Turbo mode(!!!). Then see inside my project. Show variable timer. Hide variable timer. Then save changes. This is the only way to fix turbo mode. Then wait (around 1-2 minutes). How it works: After two tries I figured out the best way to generate a Sudoku is by rows. First row, then second row and so on. Every row has different parameters to care. Check my code. I'll try to make real Sudoku game
