Mr. Marx attempts to hit to the *pissoar. For each attempt, he must select the power and angle. There is also an obstacle between Mr. Marx and the pissoar. He must therefore throw over or under the obstacle. Each successful attempt awards two stars, whereas each failed attempt deducts one star. Mr. Marx has four stars at the start of the game. Once he collects ten stars, the game is completed.
Power and angle are determined by pressing the left mouse button and moving the pointer in the direction of the throw. The force of the throw is displayed on a screen. Once we let go of the mouse button, Marx throws the piss towards the pissoar.
