In celebration of April Fool's Day, this is a bit tricky.
Rules:
Beware, some rules are tricky.
The amethyst A's are double arrow lines. The digits along the line add to the same as the digits in the circles at the end.
The pink P is a parity line. Digits along the line must alternate parity.
The red R is a renban line. Digits on the line form a consecutive set, in any order.
The indigo I is an index line. Digits reference their position on the line. The black dot separates digits in a 1:2 ratio.
The lilac L's are lockout lines. Digits in the diamonds must be at least four apart, and the digits on the line must not be between them or equal to them.
The fuchsia F is a friendly line. Digits on the line are friendly cells. A digit in a friendly cell is equal to its row, column or box number.
The orange O's are odd digits. The white dots separate consecutive digits.
The scarlet S is a slowish thermometer. Digits must increase starting from the bulb. However, the digits increase by 1 except for at the two ends.
The dark blue D is a dutch whisper line. Digits along the line must be at least four apart.
Digits in a cage must add to the total in the top left corner.
The yellow Y is a nabner line. Digits on a nabner line can never be consecutive. Why nabner? Who knows?

Thought I read the rules carefully, still had to back up a bit at one point. Very nice puzzle, thanks!
