When a newbie solves a puzzle it would be great to compare the solution to the “best” way as opposed to the least effective way with a simple numerical score.
Currently solving more by trial and error than learned patterns and not sure my solutions are optimal or poor.
I was just ready to upload a guide addition to my Puzzle solving guide, and it holds a taste of what you are after. I have let two of our best puzzle solvers loose on a puzzle and show what they do step by step. Also there is pictures of their absolutely best.
It have earlier been proposed, I don’t remember by who, to have a database accessible with puzzle solutions, that one could access as soon as one have solved the puzzle oneself. That is sort of related to what you wish for.
