Up to N Funk

Normal sudoku rules apply.

UP TO N: A clue panel (outside the grid) by row N or column N gives the total of any digits that occur before the digit N in that row or column, seen from the direction of the clue (and not including the digit N).

MYSTERY CLUES: The numerical contents of the clue panels must be deduced. Any empty panel represents some number greater than 0. A '?' indicates the number is between 1-9. A grey circle indicates the number is odd.

RENBANS: A pink clue panel indicates that the digits within the 'up to N' sum (not including N itself) form a renban: a set of consecutive digits that can be arranged in any order.

NABNERS: A yellow clue panel indicates that the digits within the 'up to N' sum (not including N itself) form a nabner: no two digits anywhere in a nabner may be consecutive.

DIAMOND DIGITS: An empty clue panel being pointed at by an arrow can have its clue determined by summing the 'diamond digits' along the arrow that points at it. Discover diamond digits by solving these mini 6x6 puzzles:
