One Loop, Two Loop

(Published on 21. July 2024, 11:48 by Belamis)

Sudoku: Normal Sudoku rules apply.

Kropki: Digits in cells separated by a white dot are consecutive. Digits in cells separated by a black dot have a 1:2 ratio.

This puzzle contains a red loop and a blue loop - Each is a one-cell-wide loop of orthogonally connected cells. The loops can't touch themselves, not even diagonally. However, the loops may touch and cross each other.

Along the red loop, digits differ by 5 or more. Along the blue loop, digits differ by 4 or less.

All cells connected by a Kropki dot are part of at least 1 loop. NOTE: This doesn't mean a loop will necessarily travel through the Kropki dot itself.

Cells containing a purple Square contain both loops. Every possible purple Square is given.

Cells connected by a Kropki dot must be part of the loop :)

Oh I'm dumb I forgot about that rule.
This was my first loop puzzle and I really enjoyed it. Thanks for sharing it!

Thanks for the kind words. Nice work solving it, this was definitely not easy for your first one. I am a big fan of the logic in loop (And snake) puzzles - Leads to some fun deductions :)
