Puzzles about Arranging Numbers on Edges of Directed Graphs

Hi,

Here’s a puzzle about arranging numbers on arrows of a directed graph so that numbers on all arrows entering each node are (strictly) less than numbers on all arrows leaving that node.

To shuffle numbers between two arrows, you click on the number on one arrow and then you click on the number of the other arrow.

determining the type of cypher used

I’m in an NFT community trying to solve a cypher we were given. We know almost all of the symbols -> english letter conversions in this 8×8 grid, but we cannot figure out what type of cypher it is. We were told it is not a route cypher or grille cypher. anyone have any clue? I would love any ideas folks have for how to determine the type of cypher. been racking our brains on it for a few days. thanks!

Help with the name of a puzzle and the solution

My grandfather had this made of wood. I replicated it with my 3d printer. The object is to switch the big square with the horizontal rectangles by sliding the pieces. I don’t think i ever knew what it was called. Over the years I have forgotten the solution also. I can remember bits and pieces of it but not the correct order. Any help would be appreciated.

Dizzy Sailor

A dizzy sailor is standing on a 15×15 square tiled board. From their initial square they are able to move to any square sharing a common side. Due to the sailor’s dizziness, after every move they immediately make a left or right turn before repeating this process (that is, they are never able to enter and exit a square in a straight line). What is the largest number of squares the dizzy sailor can walk on if they are not allowed to repeat squares and the last step of their path must end at the square they started at?
