Current record for minimally clued 7x7 Hidato (16 clues)
<sup>Note: I checked that the solution is in fact unique using [this](https://tinyurl.com/2s4hzh8p) Picat program created by SE user [Bubbler](https://puzzling.stackexchange.com/users/71652/bubbler).</sup> ### Background So back in March, I posted [this](https://puzzling.stackexchange.com/questions/125841/what-is-the-minimum-amount-of-numbers-needed-to-create-a-4x4-hidato-with-a-uniqu) 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 ### The puzzle ```lang-none +--+--+--+--+--+--+--+ |1 | |30|26| | | | | | | | | |20| | | |35| | | | |19| |37| | | | | | | | |39|13| | | |49| |40| | | | | | | | |42|43|46|10| |7 | +--+--+--+--+--+--+--+ ```
