{hi}rollerz is a challenging game full of tricky trails which have to be beaten in time by rolling your sphere and obeying the physical world of Sir Isaac Newton. But sometimes your understanding of gravity will be put to an acid test - nobody told you that you can switch gravity??? Poor you ... with {hi}rollerz you can and sometimes have to!!! Reach all timegates and checkpoints within a certain time and you will be rewarded with achievements and gamepoints to reach the top of the online scoreboards. And remember: rolling something around is the world's most appreciated diversion!!!
