Double Entendre, by James Sinclair
Normal sudoku rules apply.
Exactly one cell in each row, column, and box is a "doubler", and doubler cells contain a complete set of the digits 1-9.
A cell's value is equal to its digit, except that a doubler cell may or may not have a value equal to its digit multiplied by two. The same cell may have different values for the purpose of different clues.
Cages: the sum of the values inside each cage is equal to the small number in the top left corner.
Arrows: the sum of the values along an arrow is equal to the value in the connected circle.
Region sum lines: box borders divide each blue line into segments with the same sum.
German whispers: along green lines, values differ from their neighbors by at least 5.
Renban lines: purple lines contain a non-repeating set of consecutive values in any order.
Values in cells separated by a black dot have a 1:2 ratio.

That was very cool! I forgot about the might be doubled, might not be doubled rule near the end of the solve, which made me think I'd broken the puzzle when I placed a certain low digit in B7, but was able to correct course. Thanks for this :)

Nice one, thanks. That r1c9 is my favourite cell for some time (though r7c3 runs it close). Not as long or as hard as I was expecting but what can you do.
