Drag a line between each pair of matching colored dots until every pair is connected.
Paths must fill the whole grid with no overlapping segments — route with the entire board in mind.
Connect the pairs with the most constrained space first, and use Hint when a corner refuses to close.
Yes — it runs in your browser with no download and no registration.
Connect every pair of matching dots so the paths cover the entire grid without overlapping.
Yes, each difficulty level gets a fresh official board every day, plus an archive of past puzzles.

ZIP takes the classic numberlink idea and polishes it into a fast, satisfying daily habit. Each puzzle hands you a grid dotted with colored pairs; drag from one dot to its twin and the path locks in. The twist that makes ZIP special is the coverage rule: paths must occupy every cell of the grid, so you cannot simply connect pairs one by one — you have to weave them together like a single continuous circuit. That single rule turns a simple matching game into a genuine spatial puzzle where planning two moves ahead matters. Five levels and several board sizes let you calibrate the challenge: smaller grids for a coffee-break solve, expert boards that will genuinely test your systematic thinking. The interface is deliberately clean — draw, undo, reset, hint — so nothing stands between you and the next aha moment. Daily boards mean everyone solves the same puzzle on the same day, and the archive lets you catch up on any you missed.
