Logic Masters Deutschland e.V.

Inspired by and dedicated to the organizer of the 2024 Secret Puzzle Santa 🎅 at the CTC Discord, Wessel Strijkstra.

• Normal sudoku rules apply.
• A digit on a circle counts how many times that digit appears on circles.
• Digits joined by a black dot are in 1:2 ratio. Not all possible dots are given.
• Digits joined by an orange × sum to 10 and digits joined by an orange v sum to 5. Not all possible × and v are given.
• Draw a loop that goes through cell centers, can move diagonally but doesn't cross itself 😔, doesn't go through any orange × or v, and goes through all circles and some of the black dots. The loop must go from one circle to another circle with the same digit or to a black dot. All circles with the same digit must appear on the loop one after another without black dots in between them.
• Adjacent digits along the loop must have a difference of at least 4.
