June 30, 2026 - Threadline Daily Puzzle is now available on iPhone as a free daily path puzzle for players who want one quiet logic challenge a day.
Each puzzle asks players to trace one continuous thread through every cell while connecting numbered knots in order. The rule is simple enough to understand in a few seconds, but the route can fail if a corner, corridor, or final square gets cut off too early.
One clean thread. Every cell once. A calm daily iPhone puzzle with no ads and no account.
Threadline is built around a daily habit rather than a feed. Today's puzzle is free, solved days become part of a yearly Tapestry, and the app does not require an account. It also avoids ads, analytics SDKs, and tracking.
Why it exists
Threadline sits between a tiny daily brain teaser and a spatial logic puzzle. It is meant for the moment when a player wants something thoughtful but not loud: a board, a route, a clean finish, and then tomorrow's puzzle.
How to play
Start at knot 1, draw through adjacent cells, reach each numbered knot in sequence, and use every cell exactly once. The final knot should arrive only when the full board has been covered.
