Punch the boxes as hard as you can! You are a boxer with very low money and because you can't afford to train at gyms, you train by punching boxes! You have to tap on the sides of the screen to punch and destroy boxes and be careful to avoid sharp wood that is on some boxes or otherwise you will get knock out! Also, remember that time is limited and you have to punch boxes to earn more time. So punch as fast as you can and earn more score!
