Welcome to a puzzle that adds a simple yet elegant parity-based twist to our Daily Sudoku League! Today's Even Sum Sudoku is a fantastic variant that challenges you to think about the sums of adjacent digits. While classic Sudoku rules apply, the grid features greyed cells, each forming a pair of two continuous cells either horizontally or vertically. The key rule is that the sum of the two digits in each of these grey pairs must be an even number. This creates a clear and satisfying logical path, especially since I've designed the puzzle to be as symmetrical as possible. Are you ready to ensure every grey pair sums to an even number and complete the grid?
