Number Path Numbrix-style
Fill every cell from 1 to the final number so consecutive values touch orthogonally. Play a 120-level campaign, the date-stable Daily, or fresh solver-verified Practice boards.
Select any filled number, choose +1 or −1, then tap or drag through adjacent cells.

How to play & solving strategy
Work from either end
Select any filled anchor. Forward +1 extends upward; Backward −1 fills the same gap from its high-number end.
Read distance and parity
If two anchors are six numbers apart, their cells must be reachable in six orthogonal steps. Too far—or the wrong checkerboard parity—cannot work.
Use tight gaps first
When the Manhattan distance equals the number gap, the path has no spare steps. Those corridors are usually the cleanest place to continue.
Protect every square
A valid finish uses every cell exactly once. Avoid moves that isolate a cell or split the remaining board into disconnected pockets.
Reasoned Hint
Hint first previews a local or exact-certified forced placement without changing the board. Apply it only when you want assistance; stored answer locations are not used as the fallback.
Daily & print
Daily boards are date-stable and replayable. Printing keeps fixed clues while clearing player entries so the board works on paper.
