Good stuff…

…but I wish I could bookmark my latest puzzle(s?). I’ve asked twice, and I see others have too — it’s a shame there has been no response.

Non unique solutions

I have found two puzzles with non unique solutions. I really hate this. I have ADHD and can get quite obsessive. Puzzles that don’t work are actually painful for me. It’s actually really irresponsible to release puzzles like this.

I’m hooked!

I’m spending way too much time on these, but having a blast!

I wish the corner and center pencil marks were separate like they are on classic sudoku app. In this app, if you change one, the other changes too. Might as well not pretend they have different functions.

Very good puzzles

Bit late to this but I have only just discovered the Sandwich Sudoko variant so very happy to have found this app. Excellent puzzles however I dislike the way it automatically deletes my other “possibles” in the region/line etc when I place a definite number. It very often impacts on other decisions so prefer to review and erase myself, as with pencil and paper. Is there a way to turn this feature off? Also what do the random numbers in circles under the puzzle number on the menu page mean? Can’t find any explanation anywhere. Other than that I am really enjoying the puzzles and format.

Not Worth It

There’s a fixed list of puzzles that don’t seem to be in any particular order, so there’s no way to set up a difficulty or do new puzzles.

The interface is completely inscrutable; just a bunch of unlabeled buttons with meaningless symbols.

This is clearly a quickly hacked together Unity project meant to make a quick buck.
