Thanks for your feedback. I agree and am converting each puzzle to remove the mistake system and allow the user to click a button when they've completed the puzzle to see if it's correct.

I hear ya and I am in the process of switching them to removing the error flagging and making them work by letting the solver click/tap a button when they've completed the puzzle. Then it will tell them if it's correct or not.

Or you could only flag the inconsistencies, for example if the same digit shows up twice in the same row.

awesome!!

Different puzzles have different validation logic. So the logic varies from puzzle to puzzle. Generally we're working backwards from a completed puzzle.

Yep, it's a tricky problem. I'm currently in the process of switching the way the puzzles work so that they don't have a mistake counter and instead allow the solver to tap a button when they're complete instead. That will make mistakes no big deal. Hope it helps! I'll also see what I can do about the size of the cells.

Thanks for the feedback. The leaderboard definitely needs some love

All the puzzles are generated by the app. Each puzzle type has its own generator. Some take a while to generate and I have to do them ahead of time, but Sudoku and X Sudoku generate on the fly

email me at ChestertonTechnologies@gmail.com if you find bugs like this and I'll try to fix them. You should be able to play one puzzle of every type + difficulty without signing in.

That's a good idea. I'll look into adding that feature!

They should be unique solutions. The way I generate the puzzles requires them to have a unique solution. I've thought I found a couple that were not unique, but then both times, I was missing a cell I could eliminate. But let me know at ChestertonTechnologies@gmail.com with the puzzle number and difficulty if you find one and I'll look into it!
