My Shark Show offers players an opportunity to prove their skills at putting on a show with a great white shark and other marine life, such as an albino shark, giant piranha, killer whale, tiger shark, turtle and even the skeleton of a shark, at an aquatic theme park. The goal of the game is to increase the crowd size and earn coins from the viewers by training the sea life and showing each animal off in as positive a light as possible for the crowds by performing various types of stunts.
After the player presses the "Start" button, they're introduced to a great white shark who needs to attack meat hanging from hooks high above the water. The player uses the Left and Right arrow keys to help the shark swim through the water to the left or right, respectively, until positioned under the meat. They then repeatedly press the Up arrow key to help their shark leap out of the water. The Down arrow key allows it to dive back beneath the surface.
Every time the player successfully puts on a show for the crowds with their shark, they earn coins that make it possible for them to unlock new levels of the game. Stunts vary at each level, but include attacking a boat, attacking a stunt surfer, eating various fish, knocking down pins, jumping over or swimming under a net, jumping over hurdles, jumping through flaming hoops, jumping through underwater hoops and handling complex obstacles at the same time.
