This is a first time collaboration between myself and ThePedallingPianist, who was the only person I could think of who would willingly agree to set a puzzle like this!

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box of the main 9x9 grid.
• Doublers: One cell in every row, column, and box of the main grid is a doubler. The value of a doubler is twice the digit it contains. Every doubler contains a different digit. The value of a non-doubler cell is the digit it contains.
• German Whisper: Adjacent values along a green line must have a difference of at least 5.
• Renban: Values along a pink line must form a set of non-repeating consecutive values in any order.
• Full Rank: A value in a cell around the perimeter of the grid represents the rank of the 9 or 10 digit number formed by reading the values in that row or column from that direction, where (1) is the lowest such row or column and (36) is the highest. There are no tied ranks in this puzzle.
• When a row or column contains a double digit value, both digits contribute to the rank, with the 10s digit always appearing first. For example, if a row was 12345(6 Doubler)789, it would be read as 1234512789 from the left and 9871254321 from the right.
