Logic Masters Deutschland e.V.

Made this quick on the evening of Easter 2025 with the goal of it being fairly approachable but not immediately a fill-in either. I think I struck a good middle ground after drawing the shape and adding some givens to have some nice logic that doesn't require too much intense thought. Let me know what you think :)

Solution videos to my puzzles are posted on my YouTube channel. Try to solve without referring to it first :) I include this here as an option to increase accessibility to my puzzles. Happy solving!


Rules:

• Place the digits 1-9 in each row, column, and 3x3 box.
• German Whispers: Adjacent digits along a green line must differ by at least 5.
• Renban: Digits along a pink line must form a consecutive sequence in any order.
• Region Sum Lines: Box borders divide blue lines into segments. Each of these segments must sum to the same total. For example, R5C2 + R4C3 = R4C7 + R5C8.
• Entropic Lines: Each set of 3 adjacent digits along a peach line must contain exactly 1 low digit (123), 1 medium digit (456), and 1 high digit (789).

Solve on Sudokupad here! Everyone is welcome to solve this on a stream or video, but I would prefer you let me know when such a thing happens so I can check it out (DM me on Discord, same username phoenixaki) :)
