If you have created a program or a tool to assist Sudoku players, post a notice in this forum about the program or tool. Please include details of where the program may be downloaded from, or include details of how the tool can be implemented.
If you are a user of some existing program or tool, you can ask questions about how it works or post a review.
The old distinction between generators and solvers has been removed, if it is a program it is fair game.
