8x8 Irregular Knight's Tour

(Eingestellt am 4. Juli 2020, 18:41 Uhr von stefliew)

I got this idea from Cameron from the Discord CTC Fan Server.

Create a closed loop by drawing lines to connect cells on the grid. Each cell on the loop can only be visited once before the loop repeats. Consecutive cells in the loop must be one chess Knight's move apart (consecutive cells in the loop are not orthogonally adjacent, but other cells in the loop may or may not be adjacent). The loop must contain exactly one cell from each region of the grid.

To use Penpa to draw a line between two cells that are not orthogonally adjacent, select "Mode: Line" and then "Free" (after "Normal" and "Diagonal"), then click and drag between two cells.

Here are a couple of smaller ones. I didn't think they were good enough for a separate post so I'm throwing these in here for fun.

Extra Puzzle 6x6

For the main puzzle, for every row from top to bottom, the column numbers of the cells which the Knight lands on from left to right. (24 digits)

Note: There is an example image here that shows up on the English page but doesn't show up on the German page and I don't know why. Even if I copy the entire thing from the English page and paste it to the German page, the image still doesn't show on the German page. If you are on the German page and you can't see the image, please switch to the English page to see it. Sorry for the inconvenience.

Example: 2 24 3 13

Solution code for extra puzzles (highlight to see)
