Connect each pair of matching numbers with a path, filling every cell of the grid.
About Number Link
Pairs of matching numbers are scattered across a grid, and each pair must be joined by a path running through adjacent cells. Paths may not touch or cross one another, and — this is the condition that turns a drawing exercise into a logic puzzle — the finished paths must occupy every cell of the board. A route that merely connects its endpoints is rarely correct; it must also leave exactly the room the other pairs require. Solvers learn to run paths along walls and around corners first, since the numbers near the edge have the fewest choices.
How to Play
Drag from a number to its twin to draw a connecting path through adjacent cells. Paths may not cross or share a cell with one another. The puzzle is complete when every pair is joined and no cell on the board is left empty.
💡 Tips & Strategy
Trust the edge of the board first. A number sitting on the border usually sends its path along the wall, because the wall is the one neighbour that costs nothing — and in a puzzle where every cell must be used, hugging the perimeter leaves the open middle for the pairs that need it. Corners are even stronger: a corner cell not occupied by an endpoint must be passed through, and only two paths can do it.
Use the full-grid rule as your main weapon, not as an afterthought. Every cell must be covered, so a pocket of cells that only one pair can reach belongs to that pair, however roundabout the route looks. Conversely, a tidy direct path that walls off an empty pocket is wrong, and you can reject it without trying it.
Endpoints block as well as connect. A path may not pass through any numbered cell, so a cluster of numbers forms a fence with narrow gates, and counting the gates tells you which paths can pass between two regions. If three pairs must cross a boundary that has only three gaps, every gap's user is determined.
Avoid the beginner's habit of drawing a path that touches itself. A correct numberlink path never runs alongside its own earlier cells in a way that could be shortcut — if it could be shortened, the cells it wastes belong to another pair, and the real solution shortens it. When a path seems forced to brush against itself, the error is nearly always several moves back.
