Solving Tip: Spot Forced Moves

Some cells in a Zip puzzle have only one possible way to be reached. If an empty cell is surrounded by walls on three sides, or bordered by visited cells on all but one side, the path must enter it from that single remaining direction. These are called forced moves, and skilled players scan for them constantly. Every time you place a segment of the path, re-check the surrounding cells to see if any new forced moves appeared. On a curated 6×6 grid, there are usually several forced moves at the start that chain together. Finding them turns a puzzle that looks complex into a series of small, obvious steps. The daily Zip puzzle is the same for everyone — see if you can spot more forced moves than your friends.

Archive puzzle #259 is a Wednesday 6x6 Zip challenge. Use this replay to practice short forced moves near numbered cells, watch for building a loop shape that cuts the board in half, and aim for a relaxed archive replay.
