I advice you browse this forum, because this topic has been discussed in many threads.
You only need a solver, not a de-solver.
Remove a random digit from your grid, and try to solve it. If it fails, you must replace that digit and try another one. If it succeeds, continue removing digits and solving the remaining puzzle. Continue until you cannot remove anymore digits.
The maximum difficulty depends on the strength of your solver. If you use a brute force solver, it may produce valid puzzles, but not solvable by logic only. If you use a simple solver, it will produce simple puzzles. |
