Notice: This Sudoku uses the numbers from the other two Sudoku puzzles as conditions. If you want to solve this Sudoku, please solve Woolen Dough and Totem Pole first.

Standard Sudoku rules apply.
The board has different colored lines on it. In addition to the gray line, two cells connected by the lines may be one of the following four cases:
- Sum is 5;
- Sum is 10;
- Difference is 1;
- Ratio is 1:2.
Lines of the same color represent the same situation; lines of different colors are different and need to be inferred by the solver. Not all lines are given.
Identical pairs are directly connected by only one color line. (e.g. 2 and 3 are connected by a line with a difference of 1, they are not connected by a line with a sum of 5.)
The gray line in the board can be found in the two previous sudoku (Woolen Dough & Totem Pole) in a unique corresponding SHAPE, and the number in the framed cell is the same as the number in the relative position of the gray line in that palace in the corresponding question.
The numbers in the nine framed cells are not repeated.

The diagram below is an example of the rules for gray lines and framed cells. The right side of the board from Woolen Dough, the only two sudokus here and the left example of the same SHAPE of the gray line, so number in the right side of marked out cell goes to the left side of framed cell.
