Best Sudoku App, by far
This is a real tool for players that are serious about Sudoku. There are many many puzzles at many skill levels. The amazing, amazing hint system actually teaches you how to play better. The app is super smooth and responsive at all times. No competition.
The best user interface I have ever seen in a Sudoku game. The use of color and position to stimulate additional parts of the brain is a great plus
Already love it
Looks much more fun and colorful than most sudoku apps and has a good selection of games and an intuitive pencil mark interface
