Complete guide
Numberlink uses the independently implemented Nikoli Numberlink rules v1 profile (R368). Numberlink is a complete deterministic browser game built around paired labelled endpoints joined by orthogonal noncrossing paths so every board cell belongs to exactly one connection.
Numberlink begins with a rectangular grid containing two endpoints for each label and no pre-drawn path segments. The Numberlink deal identity and Nikoli Numberlink rules v1 are stored together. Restarting Numberlink reproduces this opening exactly.
During Numberlink, you extend or erase a label's orthogonal path through unused cells, never branch, cross another path, or pass through a different endpoint. The Numberlink engine rejects profile violations, unavailable material, and every action attempted after Numberlink reaches a terminal result.
You complete Numberlink when each matching pair is connected, paths do not overlap, and the collection covers every grid cell exactly once. The full Numberlink position determines the outcome; visual shortcuts never replace the documented Numberlink terminal rule. In the Numberlink endgame, treat uncovered cells as mandatory path capacity and reroute the most flexible pair until the final corridor is filled. Check every remaining Numberlink action before committing because its terminal rule is enforced immediately.
A reliable Numberlink plan is to route constrained border pairs first and preserve enough corridor width for labels whose endpoints divide the remaining area. A Numberlink hint is legal and deterministic. The next Numberlink hint exposes one bounded action; it never claims a forced Numberlink win. A costly Numberlink mistake is to connect a nearby pair with the shortest route while sealing an isolated pocket that no remaining path can cover. Undo supports studying that Numberlink decision, while restart preserves the original seeded Numberlink opening.
Numberlink uses paired labelled endpoints joined by orthogonal noncrossing paths so every board cell belongs to exactly one connection. That rule belongs to the Numberlink engine and storage identity rather than a cosmetic preset.
Every cell must be covered by exactly one path; merely connecting all labelled pairs with unused empty cells does not solve the puzzle.
Numberlink records its game ID, rules version, and seeded deal identity. Those Numberlink values recreate the same opening without a server request.
