In Fastone your job is to use the mouse to take the stones that fall from the top of the screen and make a pyramid type structure to balance on the line. The line will shrink as time goes on so you have a time limit to figure out the best configuration for the stones on your screen. You have to be able to balance them all on top of each other in order to make it to the next level. There are twelve levels in all. The level will automatically change when you get the configuration correct, and then it's on to more stones and a faster shrinking line. See if you can figure out Fastone!
