Relax and the Halloween Pop It game will help you with this. You'll use the pop-it to unlock different Halloween characters and props. To open the next picture, which looks like a gray image with a question mark, you need to click on all the bubbles that cover it. Pop the bubbles by clicking on them and when the last one disappears you will get a picture. The game won't require any special mental effort from you; you don't need to be smart just to click bubbles in Halloween Pop It.
