Sudoku (Full Version‪)‬ 4+

Great app

I’m visually impaired and Red/green colour-blind. This is the first sudoku app I’ve been able to use easily. I read the review that suggested having each number be a different color. Obviously, for those of us with color blindness this wouldn’t be very helpful, I could make the app on usable. Perhaps a setting where The user could choose to use the colorful set up as the default and allow those of us with impaired color vision to keep it at the black and white. I would find it helpful if as the person who suggested the colorful numbers did that the number I have chosen in either the grid it’s self or the number pad at the bottom could be bolded. That way I could easily scan for the numbers that I need. However, the way you have it now works exactly like it does in the paper so it’s not a necessity. I do like how you haveThe scoring set up. Being able to distinguish between my on edited and aided scores lets me really enjoy trying to beat myself. Thanks again for such a great app! PS: please excuse any typos as iPad doesn’t let me see my review in large enough print for me to proofread it.

Best soduku app ever

This app has the best interface and setting options. It lets you choose whether you’re picking the box first or the number and it doesn’t make you press and hold to keep keep working with the same number. It doesn’t deliver intrusive ads or kick you out if you make a mistake in the course of solving. It highlights all the squares with a number when you’re working it, entered values and penciled values alike. I only do the extreme level. other apps may seem like their harder puzzles are more difficult by comparison but it seems like most of their harder puzzles hit a point where the only way to solve is to assume one of two values and iterate it through to see if it’s a bust down the line, then go back and either lock it all in or iterate through based on the alternate value. when you’re content that you can solve any soduku puzzle and you start playing for speed instead, it’s nice to have an app that serves up a majority of puzzles that can be completed by logic not iteration.

More than one way to solve a board

After my previous favorite Tap Sudoku stopped getting updates, I tried a half dozen apps before finally finding this one, where I could enter the number first then the cell. This speeds up your ability to play and is really a must, but most apps don’t offer it. After one game, I was pleasantly surprised at how the game also keeps your top 10 times. Neat! However, after playing 5-6 times (on “extreme” naturally bc I’m an addict), I came to a point when I realized there were no certain moves left. Thinking I may have missed a hint, and being nervous about the ticking clock, I guessed and it worked. But this continued to happen and I realized these are not true sudoku boards. A TRUE SUDOKU BOARD HAS ONLY ONE WAY TO SOLVE THE PUZZLE. The boards in this app offer several. This is problematic bc you are required to make 50/50 guesses (which often both work) in order to complete the puzzle. There’s no logic as to which 50/50 cells have one or two possibilities. Therefore, there is a new component of luck introduced, and that’s just not sudoku. I love the other features and gameplay functions but I’m not sure I can support this unfortunate flaw in the game itself.

Developer Response ,

Hello. Thank you for writing.

Is it possible that when you come to a point where there are "no certain moves left", it is simply because _you_ don't see the next logical move?

The fact that your guess turned out to be correct does not mean that there are several possible solutions. It just means you guessed correctly.

Regarding your claim that when making a 50/50 guess both often work, this is simply not true. Our puzzles have one and only one solution. If you'd actually taken one guess and followed it to a solution, then the other one would not result in a solution and vise versa.

Again, when you say "there's no logic as to which 50/50 cells have one or two possibilities", is it possible that you simply don't see the logic?

Allow me to reiterate: every puzzle has one and only one solution. There is no guessing
required and the puzzles are solvable with logic alone.

If you come across a puzzle where you are unable to deduce the next logical move, you may find it useful to post it to our forums and someone from the community might be able to help to guide you to the next move (http://www.genina.com/forums/show/1.page). Or, if all else fails, you may send us a screenshot and we will have a look (sudoku@genina.com).
