Questions
What are the Nonogram rules?
Clues give consecutive filled runs in order, separated by at least one empty cell. Crosses are optional; fill all required cells to finish.
Are my game moves uploaded?
No. The board, clues and searches stay in this browser. Only safe categorical tool events may be recorded; puzzle contents, solutions and move history are never sent to analytics.
How does local progress work?
This page restores its own saved board, score and recent undo history when browser storage is available. Clear site data to remove it. It never automatically opens from the homepage.
Are new Nonograms unique?
Game boards are checked for exactly one solution before play. Custom solver clues may have no solution or several; the result reports what the bounded search proves.
