User reviews

Great

Love this App. Possibly one of my most used. Simple clean no adverts. Possibly need a new pack but happy going back through the ones Iโ€™ve done

Best Iโ€™ve found

Quality puzzles, intuitive gameplay and doesnโ€™t try to upsell you constantly. Therefore the only place I do killer sudoku.
For reference I only do the toughest puzzles (not always successfully!)

Best Killer Sudoku App on the iPad

This is actually an app version of my favorite Killer Sudoku website. Most of the same features that make that the greatest website are present here, too, including:

1. Unique solutions every time!
2. Puzzle packs available for purchase at every level, including my level, the highest one, Extreme.
3. Most puzzles I've purchased are symmetrical, which is my preference. An exception is 100 Extreme Killer Sudokus #2.
4. The timer can be turned off. I never want my Killer Sudokus timed!
5. Pencil marks available, using the same keyboard.
6. An ability to check what's been entered, looking at the whole board. Unlike some other Killer Sudoku apps, it does not show in red a number that can't be correct based on what has already been entered, which I consider to be very distracting, even though some may consider it helpful.
7. The ability to toggle between showing the numbers in entry sequence or number sequence.

Although I have given this one a 5-star rating, there is still room for improvements, mainly along the lines of settings that are present in the web version but not here:

1. Remember that the timer has been turned off between games.
2. Turn off "Undo includes cage combinations". In other words, if I am using undo, especially several steps' worth, I don't want my cage combinations reset.
3. If playing on an iPad with a Bluetooth external keyboard, an option to use hardware keyboard entry instead of the app-specific onscreen keyboard.

And one more request - Can we please have a version for Android? I have both an iPad and an Android phone, and I'd love to play this on both devices.

Pretty great, needs one more feature

Love this game and the user interface is very fast and intuitive once you get used to it. It would have been 5 stars+ if it had the ability to colorize squares individually

Ni-ice

But want iPad version to have a left handed option! Haha
