On my last puzzle I mentioned genres could result from removing rules from existing genres. And today we have one: my favorite Math Path variant, Hidato! 🔢 🛣️

… Well, Hidato did come first… but GAPP covered Math Path before Hidato, which counts for something. To be honest, I assumed GAPP must have done Hidato already when I wrote Math Path, and only realized we hadn’t when writing up the post. So now, after over 900 GAPPs, it’s finally time to cover this genre famous enough to have a Wikipedia article 😅

Rules: Place a number from 1 to N into each cell so that every number appears once, where N is the total number of cells in the grid. Every number must be adjacent (orthogonally or diagonally) to all numbers in the grid that are consecutive with it. (Equivalently, the numbers form a path from 1 to N.)

Interface Note: Answer check will accept either all the numbers or a line (diagonal submode) from 1 to 49.

These past GAPP genres are similar:
