The W-curve Order 2 line (red line) is purely cosmetic. Its internal border's path however is constrained.

Digits along the purple line are a non-repeating consecutive set in strict order.

Digits along the pink line are a non-repeating consecutive set in any order.

Digits along the orange line must differ by at least 4.

A white dot indicates adjacent cells are consecutive and the black dot indicates adjacent cells are double the value of the other cell. Not all dots are shown.

An X indicates adjacent cells sum to 10. Not all Xs are shown.
