I will be adding to this little corner of forum my QB64 code as I check them in through Linux QB64 v 1.5 (I don't need debug), they already work fine in Windows v2.0
Sudoku is by far my most used and favorite app I've created with QB64 and version 2020-08-08 has been tested allot!
The Sudoku app has 2 screens, the first is just an Info/Help screen from which you enter a level of play.
Levels are mostly determined by the number of clues you are given, the more the easier.
The lower levels are for practice or flash card like automatic skills builder. 6 gives intermediate puzzle 7 a little harder intermediate 8 would be hardest but takes longer to build for unique solution and may end up a level 7 puzzle.
9 gives you a blank puzzle and puts you in Make Mode and you can click in a puzzle from newspaper or book.
Remember to click back to Puzzle Mode when done making the puzzle.
The Puzzle screen has some menu buttons:
The first on left toggles the solution, ON OFF
The 2nd from left toggles the check cell mode. ON will not allow you to make a simple error of putting a 2nd number in row, column or 3x3 cell block and beep you if you try. Just because you are not beeped, doesn't mean it is correct.
The Load and Save buttons work with one Temp file. Just rename that file or copy and rename if you want to store a special puzzle, perhaps one that was particularly hard. Otherwise every time you save a puzzle the last one in Temp will be overwritten.
Play: Is basically clicking a number from number palette and left click a cell to answer or right click to toggle a note of that number on and off again. To remove a number clicked in, set the number palette to 0, click that in and then reset to number you want to do next.
