FAQ
What puzzle types are supported?
Grid-based puzzles (Sudoku, nonograms, mazes), logic puzzles (Einstein riddles, constraint problems), and word games (crosswords, word searches).
How is difficulty calculated?
Our solver engine runs backtracking and constraint propagation algorithms, measuring branching factor, solution path length, and required hint count to produce a calibrated difficulty score.
Can I integrate this into my own app?
Yes. Pro subscribers get full API access with JSON responses, making it easy to embed difficulty ratings directly into your puzzle app or CMS.
