Four Long Paths on One Page
Each grid holds its own route through 64 cells, independent of the three others. A sheet is a full set of challenges at one level, handy for a trip or a puzzle get-together with friends.
Writing in Small Cells
The grids are smaller here than on the single pages. Printing on A4 at full size keeps every cell large enough for a two-digit number written with a fine pencil.
Checking the Answer Keys
Every sheet has an answer key that fills each grid with the missing numbers, printed in dotted orange so they stand out from the clues.
