Logic Masters Deutschland e.V.

Jasura and I created this for the winter holiday of 2024. We wanted to release it for when the goat got destroyed, but this year it survived all through to the end. There are two versions of the puzzle, one to fit the theme and one where all the constraints have their standard colors/appearance.

All my series:
Equality Cages
EquaLite Cages
Shifter Lines
Shifter Dots



Rules:
Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Entropy (Yule goat body): The hay/peach colored line is an entropic line. Each set of three consecutive digits on the line must be one each from (1,2,3), (4,5,6), and (7,8,9). Digits may repeat on the line.

Region Sum Line (Horn/tail): Digits along each brown/blue region sum line have the same sum within each box the line passes through. Digits may repeat on the lines.

Renban (Ribbons): Digits along each red/pink renban line must be a set of consecutive digits in any order, and must not repeat.

X (Mouth): Adjacent cells connected with an X must sum to 10. Not all X's are shown.

Black kropki dot (Eye): A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are shown.

White kropki dots (Snowflakes): A snowflake/white dot between cells indicates cells with consecutive values. Not all dots are shown.
