Use the round pink pig in Pigs vs Blocks to break all the colored blocks. Which will appear at the top of the screen. Each block has a number, it means how many times the pig has to hit it in order to break it completely. The blocks will step down with each shot. If they reach the bottom of the field before they can be broken, you will lose. If you see a small pig on the field, try to pick it up as soon as possible, this will increase the number of pigs that you will use to fire at the block army in Pigs vs Blocks.
