Crazy Climber is a coin-operated arcade game produced by Nihon Bussan Co. Ltd in 1980.
In Crazy Climber the player assumes the role of a daredevil, who is attempting to climb to the top of a skyscraper. There are a number of obstacles and dangers to avoid as the player tries to navigate the climber up the building, ranging from closing windows and falling debris thrown out by the building's residents (known here as the "Mad Doctor") to giant condors, falling beams and electric wires.
Once the climber reaches the top of the skyscraper, the player's objective is to grab the runner of a waiting helicopter for bonus points. The reward is also another building to climb, with more challenges awaiting. If the player completes all four skyscrapers, he is taken back to the first skyscraper, and the game continues to become more challenging.
