Difference Sudoku

The Difference Sudoku series adds a clever numerical twist to classic Sudoku logic. In addition to standard Sudoku rules, numbers placed between adjacent cells indicate the absolute difference between the digits in those cells.

This extra layer of information transforms every puzzle into a deeper logical challenge, requiring careful deduction and precise reasoning. The series offers a smooth progression from accessible puzzles to highly demanding brain workouts, all solvable by logic alone.

Ideal for Sudoku lovers who want more depth, more deduction, and a fresh challenge without learning complex new rules.
