Great interface, clue text needs much attention

Keep ‘em coming! You keep making good puzzles for a couple bucks a batch, I’ll keep buyin’ ‘em. (The tools are handy, but I’m not taking the “average times” too seriously since they can be manipulated to solve puzzles by themselves.)

2nd additional puzzle batch has the most interesting and challenging puzzles, but needs the most textual edits of the clues...it wasn’t ready for release. Hope they clean it up soon.

Still, this is the best logic puzzle app I’ve found.

this app has lots of issues with both usability and the content. Why does it turn off my music/podcasts? I can’t listen to any outside content while playing and that alone is enough to make me want to delete the app. There is no way to highlight or select the columns or rows, so when you zoom in and out, you’re making your best guess at where the spot in the grid you wanted to mark is. Also, the puzzles frequently require you to make assumptions based on the incomplete information provided in the clues. Based on the constraints outlined in the clues, multiple answers are possible and instead you have to rely on generalized assumptions, which is frustratingly illogical for a logic puzzle. There’s other apps out there with fewer adds, better usability, and better puzzles.

fun game and love the subjects!

I just got this today, and love it so far! It works just right, and I bought the 2nd pack too. I might try the other pack when I run out. There are lots of different subjects, and they even have a UFO puzzle - definitely something for everyone! Especially in the Age of Seti and exoplanets! :) Gotta love it!!! If you like logic puzzles, this is the real deal, with lots of difficulty levels. If you've never tried logic puzzles, you're missing out in my opinion. I'm an addict now though, so watch out! It's that kind of puzzle!
