★★★★ 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.
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 me
★★★★★ Give us more puzzles!! The mechanics of this app are beyond fantastic. The puzzles range from rudimentary to challenging. The array of settings provided are plentiful to accommodate any sudoku solver’s needs. I hope they some day create a sequel to the Sandwich Sudoku app!!! I tried the chess sudoku and was let down
