In this game, the solver has to fill the grid so that each column, each row, and each of the sub-grids that compose the grid contain all of the digits from 1 to N (where N is the puzzle size). In the Sudoku X variant, all the digits also have to be unique along both diagonals.

PuzzleMe Sudoku supports the full range of Sudoku puzzles including 9×9 (with easy, medium, hard and expert levels of difficulty), 16×16Sudoku XKiller Sudoku and different sizes such as 6×6, 8×8, 10×10, 12×12 and 16×16. And PuzzleMe Sudoku also has social play, so you can play Sudoku with friends too!

PuzzleMe Sudoku has all the features you’d expect, like pencil mode to jot down candidates, conflict marking and customized L&F options. But it also has features you’d not expect, like a clever Sudoku tutor that teaches users how to get better at Sudoku. The tutor gives step by step hints for the simplest tactics, such as elimination, to the most advanced, such as “X-Wing” and “XY-Wing”, which are needed to solve “impossibly hard” puzzles.
