Incubator Q&A

Welcome to the staging ground for new communities! Each proposal has a description in the "Descriptions" category and a body of questions and answers in "Incubator Q&A". You can ask questions (and get answers, we hope!) right away, and start new proposals.

Current record for minimally clued 7x7 Hidato (16 clues) Question

+1
−0

Note: I checked that the solution is in fact unique using this Picat program created by SE user Bubbler.

Background

So back in March, I posted this question on the Puzzling Stack Exchange asking how many clues were needed to create a 4x4 Hidato puzzle with a unique solution.

Sometime after this, I took a break from doing this (probably boredom) until recently, when I decided to try and make a minimally clued 7x7 Hidato.

I have currently created the following 7x7 Hidato with 16 clues, however am currently working on figuring out whether or not this is the true minimum or not.

Goal of Hidato

Fill the grid with consecutive numbers such that they connect orthogonally and diagonally.

Goal of this puzzle

Solve the following Hidato
