More than a standard Sudoku grid
Mastersoft Sudoku has a long history on mobile devices and has won multiple software awards. It combines classic 9×9 Sudoku with a deep collection of tools aimed at both beginners and experienced solvers.
Choose from six levels, enter a Sudoku from a newspaper or magazine, use pencil-style notes and candidate tools, or ask the app for help with advanced techniques such as X-Wings, Swordfish and Jellyfish. The Apple and Android editions have their own pages because their current store descriptions and feature sets differ slightly.
