i’ve been playing this for a couple of months , and i am already on level 3,021. when i started it became one of my favorite things to play,, now it’s became an addiction. i have gotten taught many strategies for it, and it works your brain and you find yourself just moving along with a rhythm that’s been installed into your body at the point where you don’t have to think as hard as you had to on the first few hundred levels. as if your mind is capable of solving the puzzle on it’s own at some point. when you’ve reached level 2,000 or so, you’re probably going to stop for a while and forget about it, but RIGHT WHEN YOU PLAY IT AGAIN, you will be hooked like the beginning. i have never played a game with this many levels for as long as i have on this game. you have little circles to fill in your maze with and you have many many challenges to win new designs for your circles. i’ve collected all of them, because i myself, love a challenge. but i have to give the app a 9/10. only reason it’s not a ten is because of the addsss ! there is so many, but they’re short, easy to skip right on through to get right back to your game. i just wish there wasn’t as many. but anyways, as a basic “pro,” to this game, (self proclaimed title btw,) i would definitely say it’s worth the download and it’s DEFINITELY worth playing if you’re bored one day, and want to challenge your mind. anyways, i hope whoever is reading this has a great morning/evening/night, whichever you’re reading this at ! download and have fun !! all i can say :).
