Comments:
Overall, for a free app this is great. I've been playing a ton. Biggest issue is that puzzle difficulty can be inconsistent. I've had hard level puzzles that took me 5 minutes and hard level puzzles that took me over an hour. Would be nice to have a hint system. Still, for a free app, this is great.
To be fair, an unlimited, free game without ads is getting at least four stars from me no matter what, but this game is also well designed. The puzzles are challenging, and I found the double-tap for notes to be a clever UX feature. The look is pretty plain, and there's no timer, but if you complain about that on a game that's otherwise both robust and free, you're just a jerk.
Simple, intuitive, and no ads or permission requests. Unfortunately, unusable on my Samsung tablet because game overflows the screen so one cannot touch some of the entry buttons. Also it doesn't rotate and font is tiny and looks inappropriate. Some more features would be nice, such as a check for entry errors. Still like it on my phone but downrating it due to issues above.
At first I was a little dissapointed because there are no instructions on how to use the app. But thanks to Andy's review, he explained to tap once to make a note, enter same number to delete note, and tap twice to enter your answer. Now that I understand, I really enjoy the game so much more. Being able to make notes makes all the difference in the world! This is a wonderful app that's challenging,, fun, and no ads! Thank you!
Simple, fun, and non-obtrusive (no ads or begging me to rate the app or anything). The wide array of sizes and difficulty levels allow me to gradually improve, and it's great for waking up my brain in the morning. The puzzles load quickly. It's exactly what it says it is."
