Made a little progress on the game idea I’d been experimenting with. The idea is to do find a series of orthogonal (like a rook in chess!) moves that land on every square exactly once each before returning to the start, dodging walls and jumping pits.
But the squares have arrows (limiting the direction you can move out of them) or numbers (specifying the distance you must travel from them).
Every board is solvable, starting from any square. There’ll be a playable version to use on your device (with helpful features like “undo”) sometime soon, but for now you can give them a go by hand, if you like this kind of puzzle!
![A notebook is held in front of terminal output. The terminal begins with 'Start position: [0,4]' and then shows a series of 5×5 grids containing numbers: one, labelled 'Route:', shows random grid of the numbers 0 through 24; the second, labelled 'Puzzle:', contains 1s, 2s, and 3s, corresponding perhaps to the orthagonal distances between consecutive numbers from the first grid; the third, whose title is obscured by the notebook, shows the same thing again but with 'walls' drawn in ASCII art between some of the numbers. The notebook in front contains hand-drawn sketches of similar grids with arrows "jumping" around between them.](/_q23u/2025/03/20250313_100059-640x487.jpg)
