Normal sudoku rules apply.
Digits on arrows sum to the digit in the circle.
Digits on thermometers increase from the bulb end.
Digits on pink renban lines form a consecutive set of numbers (which are not necessarily in order).
There are nine doubled cells in the grid, containing each of the numbers 1-9 once and with exactly one doubled cell in each row, column, and box. Part of the puzzle is figuring out which cells are doubled. For the purposes of the arrows, thermometers, and renban lines, the value of a doubled cell is treated as twice the digit inside it.
