Killer Sudoku! App Reviews

Be careful - its addicting. Much more fun than regular Sudoku. This version is arranged well, easy to figure out, and challenging to play. I only downgraded it because it uses up a lot of charge on my iPad Air .

I use it every day. Its a great way to keep your mind sharp.

Love these puzzles. Play them everyday!

Great game, I love the variation on traditional Sudoku and the help on possible combinations of numbers, as well as letting me insert all possibilities, then removing them as logic dictates it cannot be a particular number. The only downside is limited free games (8, I think...the reason I deducted one star). I never have, nor never will fork over money for apps or enhanced apps, so will switch to another when I solve the final couple of most difficult games.

Pretty intuitive (although Im still trying to figure out how best to use the notepad.) Be aware that in order to play more than a few games, you need to buy additional ones.

Truly challenging killer sudoku puzzles, and the perfect interface for solving them. No frills or animations to eat up valuable memory space on your device. The puzzle packs are a great bargain, Ive been playing a year on the basic $5 pack and have 2/3 of the puzzles left. As for the people complaining about the hints... try an easier sudoku program and learn how to play there. Its hard to find truly challenging puzzles, dont give a bad review to one of the only apps with them because it wont dumb-down the game for you!

Love the update! Being able to cross out combinations saves me reaching for the back of an envelope to take my own notes on the harder impossible games. Auto notes make it a somewhat different game; I think Ill like trading off to play some games with them on and some with them off. The dual keypads are awesome, I wish more apps would use them. The layout and controls are easy to see and to use. Nice tools, too. ...once again deleting the app just so I can start over from the beginning. Still a favorite. Always ready for new packs!

Great game

I love this app! The calculator and combination hint features are great. The hardest levels are really challenging. I just wish I had more time to play.

This was a great game before - it is even better with the enhancements. It makes the game go a little faster.

Great interface for phone or iPad,convenient features and multiple levels of difficulty. Many, many hours of fun.

a suggestion: in the notes, make the numbers (a) always be in order, and (b) always stay in the same relative position in the box. this will make quick scanning easier.

I love this app! It brings about another way of thinking to solve sudoku puzzles.

Love playing. Wish available with larger print numbers and colors more vibrant. Also as numbers are used up maybe fading them out from the board or crossed out.

I get tired of regular sudoku, but these puzzles are a great change of pace. Various levels allow me to select the challenge Im in the mood for. Easy to use and hundreds of puzzles.

Wonderful app. I paid the couple bucks to have the extra boards and it is so worth it. The interface is great and its nice to be able to play offline as well.

This is a great portable version of one of my favorite types of sudoku! Thank you for adding two new Mega Packs, even more fun for me!

I love this app. I love the difficulty of the games (I usually play the extreme ones). As a retiree, it keeps me sharp.

This is easy to manipulate and levels are well done!

Sudoku Killer much more challenging than regular Sudoku. I highly recommend to anyone who likes playing Sudoku puzzles !!!
