tightpaul, what do you have to do in that game?
Ok on your right hand side there is a tube that will start filling up with water, you have to stop it getting to the top. It fills with water the more times that water falls from the sky and spills over the edge. To stop it filling over the edge you have to build up lake walls using the pieces falling from the sky. Move them around with your mouse, rotate them with the right mouse button, accelerate their fall with the left, just like Tetris. Build walls to make squares, put the water in, extinguish with the fireballs, etc etc. Gets addictive.
