The title of this game says it all! Your reactions will be brought to the extreme, your mouse will suffer like it has not suffered before, your fingers will cramp from pain, and your face will show strange grimaces of tension and excitement.

But the best thing about all the pain this game can cause is that you will love it all way through.

We ourselves cannot tell why this free downloadable game causes you to suffer and enjoy.

There is nothing more to it than clicking 15 randomly positioned and numbered squares in less than 6 seconds.

Oh yes, sounds easy, but if we tell you that you have to click those squares in exact order from 1 to 15, well than 6 seconds my sound as a science fiction.

Believe us, it is doable, we made it, but you may not have what it takes to get there! Or do you?
