In this game, your objective is to smash/crush as many roaches as possible before they go away. Use your finger to squish/blow up nasty cockroaches before they increase their speed which will happen every 30 seconds. When a roach leave the screen (or escape), a point will be deducted from your lives and you have up to 10 lives. A green roach will appear from time to time which, if smashed, will give you an extra life.
