Gemcraft maze! In this game you need to do everything in your power (with the help of magic stones! ) to stop the evil get at the end point. To create the best defence you need to create the triple gem as these get very high bonuses! You can also place towers to shoot the evil to prevent them to get to the end. Place a tower in the area where it can access a lot of the path and so it will have maximum impact. There of different levels to work your way through, but keep in mind that each level does get harder so you will have to come up with a strategy!
