Rules: Normal Sudoku rules apply. Put the digits 1 to 9 once each into each row, column and 3x3 box.
Doublers: One cell in every row, column and box is a doubler. This cell has value equal to double its digit for the following rules. Each of the digits 1 to 9 appears exactly once in a doubler cell.
Renban: Values on a purple line form a set of non-repeating consecutive numbers in any order.
X-Sums: A number on a renban line outside the grid gives the sum of the first X values from that direction where X is the value next to the number (X can't be greater than 9).
