Hello, this is my first puzzle in this site :)
It needs a mix of rules, in addition of those of sudoku, I hope I can explain them clearly here;
1. Sudokus have multiple solution if solved singularly but only one when solved in couple.
2. Diagonals must contain every 1-9 digit as well. Numbers are all different in pentominos.
3. Each shape in puzzle 1 has an exact correspondance to another shape in puzzle 2.
4. The position of each shape in puzzle 2 is different from puzzle 1.
5. No "complicated technique" should be necessary to solve.
Solution code: Insert the 18 digits pointed by the red arrow in sequence, no spaces.
