16x16 Sudoku Challenge HD

Quite challenging. Especially since it does not provide some of the visual aides that other puzzles provide. A bit more work needed to accomplish the puzzles and I really like it that way.

there is no zoom and for such big puzzles it is needed. also, it is missing the highlight of a number when you touch it, it is really difficult to understand which cells a number cannot go in

Some standard features like error checking would be helpful. Good 16 x 16 puzzles.

It would be nice if we could check for errors before we completed it.

No error checking and no way to put pencil marks in with one touch.

Best 16 x 16 sudoku

Have played this on old Samsung tablet and no issues. Current lenovo tablet doesn't check the puzzle on completion so puzzle never recorded as complete. Will never get to level 2! ????????????

Way to waste some time when there's nothing else to do.

Would help if you highlight the numbers being played

Very chalenging, took me a while to get a grip on the best way to solve the grid

Love easy to use 16 cell sudoku!

Thank you for removing the blinding background. I enjoy this app, but wish the saved fields would stay saved until restored. Coming back to the game after a break seems to make it forget the previous saved fields. I would rate it a 5 if there was a checker for wrong fields. Don't want the solution but a checker to make sure I am on the right track could save hours of wasted time.

Love these games. This one has the bones. It would work for me if 1) errors were highlighted and 2) depleted options greyed.

Just need more levels. I also would request is that the penciled in #'s to larger. To be able to read the little penciled in numbers. Especially, in the harder levels. Other than that, I Love this game.

It would be nice if the number or alphabet is highlighted. This will ease the eyes from searching round and round for the number.

Nice been waiting for this.

If you like sudoku, you will love this, I want to keep on playing,

I've been looking for a decent app like this for quite a while. I love the 16 x 16 puzzles, but you're lucky if there is even one in a puzzle book! When I did find one I'd run off copies so I could do them over and over again. Now I've got this great app! It's true, it could use some tweaking, but it is still the best one out there. I'd love to see more "fields" added, I could sit and do these all day. Thank you so much.

I have done 5-6 of the first set of 16x16's without pencil marks. The letters are small but that is because I use a phone- a tablet would be easier. The star isn't as bright once you fill the puzzle in. More puzzles please!!

The star or sun in the background of the puzzle is obnoxious and unnecessary. Please remove it. The app will be much more acceptable.

Im bk and figure why not. Words w frens ok but i need more stimulation so im dwnloading again but on a newer phone.

...though I do wish the background star was optional, it's too bright and distracts from the game. I would also love more puzzles added/updated :)

I hate the star, it's almost blinding. Please remove. If I had a migraine it would be so much worse! It would help if you crossed out the numbers/letters when you have them all on the board. Also, when you find you've made a mistake there's nothing to help you figure out which one is wrong.

I too dislike the star, it is blinding and distracting. I enjoy the challenge this game provides, but a helpful addition would be if all numbers and letters used could be shaded out to only highlight those left to play.

Love the bigger Sudoku puzzle,i get bored with smaller ones. Need to add more 16 x 16 using ABC's. Also need a way to sync my solutions online, had to factory reset tablet, I was on 3rd level # 8 and lost all previous won puzzle and had to start over. Have had to delete app. 3 times, start over. Why doesn't check solution work. Don't want solution, just check when I do get stuck, instead reset. Need to change color of puzzle, blue & silver hard on eyes!

Fantastic fun and challenging at times

I love the decent number of puzzles, but most other sudoku games have features that would be a godsend here (i.e. row/column/cell, matching numbers, reverse input modes) As option to turn off background images please!

"Select tutorial from the menu" - and exactly where is the menu? Uninstalled.

I love a challenge !!!

16x16 sudoku

I've downloaded a lot of sudoku apps and this is the best one! It is hard enough to keep my attention and lets you put possibilities in each square! It's the first thing I download when I get a new phone!
