Dumb Zombie is an interesting ricochet puzzle shooter where you have to kill all the zombies with a limited number of bullets using the surrounding objects. To start, press "Play", the arrow at the bottom, "Ok" and the first number in the list. Hold down the left mouse button, point the dotted line at the target and release the mouse to shoot. To move on, press the double arrow. Shoot the stone ball: it will roll down the hill and crush the zombies. If it did not work out to kill the dead, click the green button with two twisted arrows to restart. Also use the ricochet: shoot at the blocks so that the bullet bounces off the zombies.
