Every number in the grid appears exactly twice. Your job is to join each pair with a single path that runs from square to square across or down, never diagonally.
Paths may not cross each other or share a square — and when you are done, every square in the grid belongs to some path. That last rule is what makes it a logic puzzle rather than a doodle: a corner square has only two neighbours, so a path must turn there; a square squeezed between two paths has only one way out.
Every puzzle has exactly one answer, and the Genie can talk you through each link, pointing at the squares it means.
Join each pair of matching numbers with a path across or down; paths never cross and together fill the grid.

Yes — the puzzle is only solved when every square is on a path. That rule is what makes the logic work.
On harder grids a few links are given so that the puzzle has exactly one answer that logic can reach.
Yes — every puzzle is checked so that one answer fits, and the hints can reach it step by step.
