Solve Sudoku, Str8ts, Killer Sudoku, Jigsaw Sudoku and Kakuro on your iPad with these daily puzzles from Andrew Stuart and Jeff Widderich. These puzzles will suit beginners to experts because within each puzzle are four grades - making a total of twenty puzzles available. Every day you can request a new set of each puzzle (use the "New" button on each player) or you can keep working on the current puzzles.
Progress is always saved for each puzzle. Leave or quit the app at any time and come back to an unfinished puzzle. There is a full undo/redo and you can check your progress if you are stuck.
We're very proud of these puzzles - they come from the same stock we regularly send for print in newspapers around the world so we know pretty quickly if we're not producing the best puzzles. We have been making classic puzzles since 2005 and Str8ts since 2008 and hundreds of solvers have helped us hone the logical strategies we use to make them. Because we use logic to make and grade them we are very confident of the grade spectrum they have been placed on and we can also say that the different between the easiest and the hardest should be very noticeable. So whether you are a novice or a pro there is a puzzle to match your skill.
We absolutely guarantee a single solution and theoretically you should never need to guess. Because of the strategy logic we use, even the hardest puzzles have a logical pathway to the end, although it might be obscure to say the least. If you want to check the puzzles or are stuck, we have Sudoku solvers at www.sudokuwiki.org and a Str8ts solver at www.str8ts.com. In fact you can find a wealth of information about us, the puzzles and tips and strategies at these two websites.

Ratings and Reviews
Great for Sudoku lovers
If you like Sudoku and want more of a challenge or a different twist, this app is great. Five apps, four levels, new puzzles every day. I recommend it.
Better before upgrade
The game play was much better before the recent upgrade.
Before, I could play, close app, and return to game play.
Now, closing the app wipes all completed levels. This forces you to complete all 5 levels before closing the app. You can switch apps, just don't close it!
The highlighting is a joke. For example, if I select '2', the app will highlight all cells with '2', but ONLY cells containing a single number '2' - no cells with additional numbers. The highlighting only shows the cells which contain EXACTLY what you've selected.
I'd gladly "un-upgrade" if I could.
With Family Sharing set up, up to six family members can use this app.
