"If you enjoy sudoku on paper, youll love this app."
"Simple, clean... just the way you want it if it were on paper."
"...the controls for marking estimates are the best I have seen yet."
Possibly the cleanest, simplest, most easy-to-use design for a Sudoku iPad app. Instead of distracting backgrounds and bells and whistles, we’ve tried to re-create the pencil-and-paper feel of doing Sudoku puzzles.
But we’ve also included tons of advanced features to make gameplay easier.
• Mark cells with notes.
• Automatically remove marks as you set other cells.
• Automatically set marks in cells, to save time.
• Swipe to see missing numbers in rows, columns and blocks.
• See number conflicts in rows, columns and blocks.
• Undo each action, all the way back to the start if you want.
• Set bookmarks so you can quickly undo all the way back to a specific point in the game.
• Check your work at any time to see if you have made any mistakes.
• Reveal the correct number in a cell if you are stuck.
• Each game you start can be continued later. You can have multiple games going that you can return to at any time.
• See a journal of every puzzle you have completed with the date and other information.
