PlayZipGame - Free Zip logic puzzles, official history
PlayZipGame is a free browser-based puzzle game built around Zip, the path-tracing logic puzzle. You can play the verified official-history board of the day, browse more than a hundred archived boards, or switch to 50 curated practice levels that ramp from compact 4x4 starters to full 8x8 grids. There is no countdown, no scoring system, and nothing to install: open a tab, drag a path from 1 to N, and every cell must be visited exactly once. Your best times are saved locally.
