Printable Numberlink puzzles
Four packs of Numberlink to print at home or in class – eight puzzles in each, solutions at the back. Every puzzle is proven to have exactly one solution.
How to use them
Print on A4 or Letter; the boards scale to the page. Draw each thread with a pencil from cell centre to cell centre – an eraser is your friend on the expert boards.
The rules
Connect every pair of equal numbers with one thread:
- Threads run horizontally and vertically from cell to cell, never diagonally.
- Threads never cross and never share a cell.
- Every cell of the grid is used by exactly one thread.
- A thread never touches itself: no two of its cells lie side by side unless the thread runs straight from one to the other.
