The Griddle

In this special sum sudoku puzzle, you're left with very little to go on except some values that represent the sums of the shapes. Instead of just digits, you also have unknown X and Y values to figure out while solving!

What is all this?

The Griddle is a puzzle site/blog created by David Millar. It's full of free printable puzzles that you can download as PDF files. Updates come often and feedback is always appreciated!
