Normal sudoku rules apply. Place the digits 1 to 9 in each Row, Column, and 3X3 box. In addition, the following constraints apply: Zipper line, Thermo, Same difference line, German whispers, Renban, Between line, Modular line, Entropy line, and Chinese whisper.

Zipper line (2): Digits an equal distance from the center of a lavender 'Zipper Line' sum to the digit in the middle of that line.

Thermo (First 0): Along thermometers, digits must increase from the bulb end.

Same difference line (Second 0): Every pair of adjacent digits on a turquoise line has the same difference.

German Whisper (F and E): Adjacent digits along a green German Whisper line must have a difference of at least 5.

Renban (first O and parts of W and S): Digits along a purple renban line form a sequence of consecutive digits in any order.

Between Lines (Both L's): Digits along a yellow line must lie strictly between the digits in the attached circles with respect to value.

Modular line (second O): Any set of three sequential cells along a teal modular line contains one digit from (1,4,7), (2,5,8), and (3,6,9).

Entropy lines (parts of W and S): Each set of three consecutive digits on an orange line has to contain a low (1,2,3), a medium (4,5,6), and a high digit (7,8,9).

Chinese whisper (R): Adjacent digits along a red Chinese Whisper line must have a difference of at most 2.
