Normal sudoku rules apply.

Grey lines (the “2” and the “square-root”) are palindromes which read the same in both directions.

Digits on the pink line are consecutive, but may be in any order.

Digits on the “4” thermo must increase from the bulb end.

Digits separated by an X sum to 10; ALL such X's are given (negative constraints apply).

Digits separated by a black dot have a 1:2 ratio (not all such dots are shown).
