A new Daily Challenge every day, five ways to play, and head-to-head matches with a friend. How long can you keep your streak going?
Sudoku Mind brings five kinds of sudoku together in one clean, focused app. Play the classic 9×9 grid, add up the cages in Killer Sudoku, watch the diagonals in X-Sudoku, fit digits into the jigsaw regions of Irregular Sudoku, or take a quick break with 6×6 Mini puzzles. Every puzzle has exactly one solution, so you can always solve it with logic alone. No guessing.
FIVE WAYS TO PLAY
• Classic Sudoku: the traditional 9×9 grid, from Easy to Master
• Killer Sudoku: each cage shows the sum of the digits inside it
