I’m giving this app 4 stars for the concept. However, here are my problems.........1- It is glitchy because sometimes you size it close and you get 0%. That is weird. 2- I got this app on App Advice for free when it is usually $1.99. There is an advertisement every single time you try again. So here is my question......do you have the ads when you pay $1.99 also? If not, why would it be put up for free for a limited time with ads? Not much of a bargain. I thought maybe in the settings I could go pro for free. Nope! I’m stuck with the ads. I won’t keep playing that way.Other than that, it seems like a fun game to challenge me.

So many puzzle games I try, then delete. Too easy. To hard. Too dumb. This game is “just right”. If you want to make it more challenging, see how many times you have to do each one until you get 100%.Or stick with the easy mode and enjoy passing the levels with a 90%.Really great game to pick up and play while waiting in line, or when you have just a few minutes.

Save your time. I thought I’d try this app during a free promotion. After 5 minutes I deleted it. The idea is to match the size of the object that flashes on your screen, which worked the first round. The second round I tried about 10 times, getting within 95% or better each time (dotted lines appear to show you how you did) but each time I was below 70% sometimes 0. I could not get past the second level because of this app error. Plus, as someone already mentioned, the free version still has ads.

Had trouble at first with my guess being erased or changed at the last second before scoring me. Finally figured it only happens if I use 2 fingers. Fun game, but frustrating glitch.
