Questions
What are the Block Puzzle Solver rules?
Every immediate placement is evaluated. The optional entered-piece sequence search is bounded; it does not predict future random pieces.
Are my puzzle inputs 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.
