Free printable numberlink
Numberlink, also called Arukone, is a path puzzle where each pair of matching numbers must be joined by a single trail. Paths move only up, down, left, or right, they never run diagonally, and they never cross or share a cell. On this page the 10x10 grid also uses every square, so the paths have to pack the whole board. Solvers who like connecting-the-dots logic more than arithmetic, and who enjoy watching a grid fill without leftover gaps, tend to like Numberlink.

Peek at the solution
This download is a 6x9 inch high-resolution PNG of that 10x10 puzzle, with pairs numbered from 1 to 20, plus a matching solution PNG of the finished paths. There is no signup. Print the page and draw the connections with a pencil.
How to play
- Find each pair of matching numbers from 1 through 20 on the 10x10 grid.
- Join a pair with a path that moves only up, down, left, or right.
- Never let two paths cross or occupy the same cell.
- Use every square on the board; empty cells are not leftovers.
- Check the solution PNG when the grid is fully packed.
Print at 100% scale on letter or A4 paper so the 10x10 cells stay wide enough to draw each path.
Frequently asked questions
Where is the Numberlink answer key?
A second PNG on this page shows the completed paths between every matching pair. Download it with the puzzle if you want to confirm a connection, or keep it closed until every square is used.
Does this Numberlink cost anything to print?
No. The puzzle and the solution are free PNG files, and you do not need an account to download them. Print copies for personal use; this page is not a paid PDF and has no email gate.
Who is this 10x10 Numberlink a good puzzle for?
It suits solvers who like packing paths more than placing digits. Twenty pairs on a 10x10 that must use every cell is a proper sitting, so it fits teens and adults who already enjoy flow-style logic. Younger solvers can still start with the short pairs that sit next to each other and work toward the longer ones.
How should I print this Numberlink so the paths have room to draw?
Print the PNG at 100% scale on letter or A4 paper. The 10x10 cells need to stay large enough for a pencil trail between the numbers. Avoid fit-to-page, which shrinks the 6x9 layout and crowds the two-digit labels.
