Sudoklue 4+

Absolutely perfect. Can’t fault this app. The developer responds to suggestions and any advice you want. Unlike the other sudoku apps, this one will give you tips and helps you to develop strategies and systems to enable you to progress. It doesn’t simply tell you what to do, it supports your learning and decision making.
I am so grateful for this app as I have learned so much. Brain gym and totally affordable.

What’s more none of this bloody money grabbing subscription bollox.

The latest update adds a quick number bar, very nice, but why does the teach me section now need to scroll! Surely those large white buttons at the bottom could be shrunk down a bit, they are far too large as it is. Failing that shrinking the main board a tiny bit or using up a bit of the white space would give enough room. Maybe an option in preferences to lose the jumbo UI elements or be compact or something. I would also say that it would be nice if it remembered the number you had selected. So for example, I pick ‘2’, then go to a cell to remove 2’s from it, as soon as I close that box (which also appears to have grown!) then all the numbers are deselected. I don’t know about anyone else but I tend to try number by number, so if I am looking at ‘2’s then I would like those to stay selected until I choose a different number or click off the board to deselect all numbers. It’s a small point but an irritating one. Just remember what I had selected when the popup number box was activated and then when it is deactivated put it back! Oh, and one last one, an option to restart the current puzzle would be good. I forgot, one more ‘last one’, please, please can we have a landscape option, I love this app it is easily the best sudoku app but don’t force me to keep switching to portrait mode.
If a number isn’t a given then pressing it does nothing, it doesn’t highlight it in the notes.
Support is non-existent, raised an issue 28th March, it’s May now, nothing.

If you’re trying to learn without having to put pencil marks in every single cell, good luck. Using Snyder notation isn’t supported, when looking for next steps it just tells you to keep annotating.
