Staircase Serpent [YYJ Pack]
(Eingestellt am 28. Februar 2026, 01:00 Uhr von yttrio)
This was originally created for the Yin Yang Journey puzzle pack. Links to previous puzzles in the pack are below:
Go Yin Yang
Through the Caverns
Sandwich Break
Rules:
Normal Sudoku rules apply.
Yin Yang Snake: Draw a one-cell-wide snake of orthogonally connected cells that does not branch or touch itself. The non-snake cells must form a single, orthogonally connected area, and no 2x2 area can be either fully snake or fully non-snake.
The snake acts as an entropic line: each set of three adjacent digits along the snake must be one low [123], one medium [456], and one high digit [789].
All cells connected by a white or black dot are on the snake. Digits separated by a white dot are consecutive. Digits separated by a black dot have a ratio of 2:1. Not all possible dots are necessarily given.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Note: For 6x6 Sudoku, the entropic sets are [12] for low, [34] for medium, and [56] for high
Play the example in SudokuPad.
Lösungscode: Digits on the snake in row 5 (left to right) followed by digits on the snake in column 5 (top to bottom)

normally, a yy puzzle can never be level 1, but the SNAKE is highly constrained.
the rules should say that DIAGONAL touching is not allowed

This was so much fun, and I managed to solve as a beginner with a bit of prior knowledge of yin yang rules. Thank you :)

Very nice! I raced through this, finishing in around 17 minutes. As @wuc says, being familiar with the rules makes it fairly easy. But it was still very enjoyable. This would be a great introduction to Yin Yang puzzles for people who are new to them.
Thanks for setting!

Very nice mix of rules. With experience in all rules it is a 1*. Compared with what you must bring to solve it is rather 2* to me. Great setting thx.
