Practice one difficulty repeatedly
Use the generator when you want fresh boards at the same level instead of moving through the archive in order. A useful session is three puzzles plus one note about where you got stuck.
If you get stuck on generated boards, open strategy guides or validate the position in solver.

Generator Guide
Use generated boards for practice, not just volume
This page is an entry point for creating a board, testing one difficulty, and returning to the strategy guide when a pattern stops you. The learning value comes from the loop: generate, attempt, inspect the reason, then retry on a related board.
Find the weak technique
When a generated board stops you, do not jump straight to the answer. Check where the progress stopped, read the next-step reason, and return to the matching strategy page.
Check before printing or sharing
Generated boards are meant to have a unique solution, but printouts and study notes should keep the board, answer, and difficulty together. Verify the final version before distributing it.
Before you rely on a generated puzzle
- Random generation is not a study plan by itself. Pick the technique or difficulty you want to train before starting.
- Solving harder boards repeatedly will not automatically fix missed basics. If you stall, go back to the strategy guide.
- If you reuse a generated board outside this site, keep the puzzle and answer paired and check the usage context first.
