A simple but great app. It's rare to find logic problem apps as it is. I've made 40 purchases and I'm happy with everything! The game play is great, the stories are cute, you get used to it after a while. I do have ONE major issue. You can't reset all your puzzles in one go and you have to do them individually. When you have 4100 of them it's a bit difficult. Also it would be handy if they could go into puzzle size once completed. I like to replay the big grids but have to go through all 4k

Thanks so much for that glowing praise :blush: - and all that support via purchases! Edit: After a recent update, now you can clear all puzzles with just a few taps. Happy puzzling! Cheers, Michael

I'm enjoying it so far. I used to demolish these puzzles as a kid so it's nice to find one without adds. 2 things I am finding a bit frustrating, and I can't turn them off, is that once I have technically matched up each answer it jumps to the finished stats screen, but I like to fill out each box and see a complete board. I would also like the option to turn off the auto fill of crosses when I select a correct answer. Turning off both these things would also slow me down completing them :)

Hi, thanks for that feedback. I’ve just bumped these ideas higher on the list. We would still want to stop the timer when “solved”, but we’re looking at a good way to seamlessly allow a finer experience for those of us who like completing things!

If you like logic puzzles, it's a great download. No ADS, if someone says there is, they aren't telling the truth. The free puzzles start with some very simple level ones, right up to my brain hurts puzzles. Sometimes I have had to make a guess, but I'm guessing I'm not reading something correctly. But overall it's well worth a download.

What’s new
The app now remembers where you were, even after your phone puts it to sleep. Switch apps, come back, and you'll land right in your puzzle, not the main screen looking for the started puzzle, or scrolling to find your favorite section. "Next Puzzle" works every time too.
