You are a penguin that loves gems and you have a simple fish as a weapon. Target gems by moving your mouse, set the angle and distance and press left mouse button to shoot. As longer the distance of the aimer from your cannon is, more powerful your shot will be. There are 42 levels that have to be passed and each one is getting more exciting than the previous. On the bottom of the screen are the number of ammo that you can use per level, your score and the overall rank. Keep on trying to be the best, shoot ammo as less as possible and gems of same color in a row to earn AAA rank see the beautiful gems and make sparkling fun!
