Have you ever been sitting in class wondering what to do with your spare time, perhaps you get all your work done or its friday and the teacher gives you permission to play games on the computer. (we all wish that could happen everyday right?) Anyways, as you know most of the games at school are blocked by filters or other proxies, making it so you cant access any of the games on a particular game site.
I would recommend personally to try something a little different, when I was sitting in class for long hours I would search for game sites that are not blocked, a game i would often play was called Toss The Turtle Hacked.
In the game you toss the turtle from a canon, you keep earning cash to upgrade your canon and props to make the turtle go further distances. But in the hack version everything in the store is unlocked. Bigger canons and heavier weapons to make the turtle launch even further then you can imagine! I myself have gotten the turtle all the way up into outerspace! In the game you can hit explosives that are on the ground and in the air, birds, and characters to give you a little bounce forward to add some distance.
In review i would rather play the hack version because it allows you to buy newer accessories right from the start. It gives away the challenge to the game but in my opinion i would rather play the hacked game, its a lot more funner. Go play both games and decide on which one you like at freegameshacked.com. Either the hacked version or the original.
