Tunnelling Palindromic Snake, Anti-Knight Sudoku
(Eingestellt am 1. Mai 2020, 04:42 Uhr von Aang11597)
Rules:
- Normal Sudoku rules apply.
- Anti-knight: no two squares with the same value may be a knight's move apart (horse or knight from chess).
- Tunnelling Palindromic Snake: A 'snake' (a path that is one-cell wide and does not touch itself orthogonally or diagonally) moves its way through the puzzle.
- The shaded areas represent the head/tail of the snake.
- The numbers in the cells that make up the snake will form a palindrome (the same numbers read both forwards and backwards) from head to tail.(see Figure 1).
- The circles within the 9x9 represent a location the snake will either tunnel or emerge and will contain the same number as its counterpart(see Figure 1). Note:These duplicate numbers are only counted once for the palindrome.
- The o's outside the puzzle depict how many single cell portions of the snake are visible in that row/column. As such, they also depict a column/row the snake cannot turn and must continue forward(see Figure 2).
- The +'s outside the 9x9 show the only rows the snake can turn in(see Figure 2).
- Lastly: no segment of the snake from head/tail to tunnel nor tunnel to tunnel may be fewer than 7 cells in length. (IE you cannot move 3 cells from the head into the tunnel).
Note: The palindrome in this instance would be '54345' not '543345' because the 3 is counted only once. These two tunnel/emerge points are linked and contain the same number.
Note: Column 4 and Row 3 lack an 'o' symbol because both contain a portion of the snake longer than one cell.
The Puzzle:
Lösungscode: Palindrome, row 4, column 8 -- Format: #####, #####, ##### Note: The tunnel/emerge point is a single number, do not enter it twice.

Hey thanks! The way I made it and solved it myself I was swapping back and forth kind of, but I'm not the best at solving Sudokus either haha
If I make another, I'll try to keep that in mind! :)

Thanks! Just wish I could better gauge the difficulty of it. Still not sure how difficult it is in the end.

Interesting and original. Many things to think about simultaneously.

Great combinated puzzle. And don't worry (related to your forewarning) there is only one unique answer.
