Community Insight:

So many puzzle games we 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.


It's fun. Like one of the other reviewers our default language was also set to Korean, but it's easy to change it. Also we haven't seen an ad yet and we're on level 16 so that's cool. Overall a good time passer.


We love this game. However too many ads. Option to buy.


Sometimes, the app doesnt hold the moves you make, & you have to replay several times to get an accurate measure. Please fix it.


Save your time. We thought Id try this app during a free promotion. After 5 minutes we 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 we tried about 10 times, getting within 95% or better each time (dotted lines appear to show you how you did) but each time we were below 70% sometimes 0. We could not get past the second level because of this app error. Plus, as someone already mentioned, the free version still has ads.


What a different game! Whoever thought of this has a great imagination. We just love it. Now, how do you unlock the normal and hard levels? Do we have to get all 25 at 100% on the easy level first? Dont see an update for the app so the levels are still locked. Help.


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


Im giving this app 4 stars for the concept. However, here are our problems……… 1- It is glitchy because sometimes you size it close and you get 0%. That is weird. 2- we 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 our 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. We thought maybe in the settings we could go pro for free. Nope! Im stuck with the ads. We wont keep playing that way. Other than that, it seems like a fun game to challenge us.


A good puzzle to pass some time but many times after we have left our sized guess and we press the go button a much much smaller sized symbol that we know we didnt do comes up for comparison. After it gets fixed Ill give the game a 4 or 5 star rating.


The game is fun and has a neat concept. However, many times after touching the check button, the size of our submission completely changed or disappeared. If this can be fixed, Ill change our rating to 5 stars.


We want to play this game…but need some help. The instructions are not in English. Thanks.


We would make the size perfect, click check and it would resize the image giving us a low score, very frustrating.


Saw this game on touch arcade. Didnt expect this game to be this addictive. Its really light and easy to play. GREAT TIME KILLER.
