Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.

This puzzle’s really tough, I think. The Weighted rules do play in nicely for the break-in.

Rules – Follow regular Sudoku rules. Additionally, a clue outside gives the sum of the first 3 numbers in that direction. Also, the numbers in shaded cells will count for double their values for any sum they are part of.

Rated – Hard.
