Black-dot Mamba
(Eingestellt am 10. November 2023, 20:55 Uhr von yttrio)
Rules:
Normal Sudoku rules apply.
Cells separated by a white dot are consecutive. Cells separated by a black dot have a 2:1 ratio. Not all possible dots are necessarily given.
Construct a one-cell-wide snake in the grid of orthogonally connected cells whose endpoints are given by the diamonds. The snake cannot branch and cannot touch itself, not even diagonally.
-- Every cell on the snake must have a 2:1 ratio with at least one other orthogonally adjacent cell that is also on the snake.
-- Orthogonally adjacent cells are allowed to have a 2:1 ratio if and only if both cells are on the snake.

I really enjoyed that one, though I am partial to snake puzzles. Some really lovely logic throughout, and a nice bit of colouring at the end to disambiguate the primes. Given my completion time I’d probably grade it 3 stars as I hardly ever manage to do 4 star puzzles in under a hour. It’s a lovely puzzle though. Thanks Yttrio.

Very cool!
Challenging, but I could continually make progress and therefore never felt stuck or frustrated!
