What you can do here
Play online puzzles selected and validated from the standard board banks, enter a board manually, or use a screenshot to align the grid and correct its colored regions. Play difficulty follows the source groups; it is not a new rating measured by this site. The Solver checks conflicts, offers rule-based hints where available, and finds an answer for the exact board you entered.
How to read level guides
Each guide shows its own board, checked answer, and reproducible deduction steps where available. A reference guide names its simulation conditions and links to the Solver so you can work with the board you actually see. These guides are not presented as official answers for every player.
