Mutant fights are being held around the world: the European cup, the American cup, the Latin cup, the African cup and the Asian cup. The winners of these matches will compete against each other in the World cup, a spectacular ending! Build your own mutant dog and let it fight against the other monsters. Every time you win you receive new genes which you can use for the next fight.
Drag the different genes (right window) to the DNA window and click on 'mutate' to create a mutant. During the fight you click on the attack (or defense) you want to use located at the bottom left of your screen.
