4 stars: I love this game and I've had it for 10 days and I'm on level 766 already! My only problem with it is the special level which you get every 94 levels as mine always skips levels which means that I struggle to complete the special level :-(
5 stars: This is a super fun game and very addicting. Its also teaching you lots of random things! But it ia kind of annoying when you are super super close but it doesnt count it...and when there are adds after adds. Overall, i rate this 5/5 stars! Super fun!
4 stars: The game is a lot of fun, would just be nice if all the answers were correct (and if all correct answers would be recognized as such ie. ROYGBIV!). Would also be nice if being a fraction a pixel outside of the object (or between the parts of it) didn't result in a 93° (94° being a correct answer) These issues, however, only account for a small fraction of the questions.
3 stars: This is a pretty good game. A little heavy on the paid aspect, especially for the amount of ads, which is pretty heavy. (1 every 3 or 4 rounds)
3 stars: Great idea. Using a pin for a correct guess is a shameful money grab though. Adverts for 15 guesses and then the same advert for nothing between every couple of levels. A correct answer shouldn't cost you a 'life'
5 stars: is good, tests common knowledge, but we all hate waiting to progress and i am not going to use real money to buy pins. Maybe include a challenge where you can get maybe 10 pins.
3 stars: Great game, ...
