Pro Bowl is a souvenir in WarioWare Gold. It is a minigame which can be unlocked in the game's Toy Room. Pro Bowl is quite similar to the microgame Pro Bowling, in which the player must use a stylus to roll a bowling ball to knock down a set of pins. However, unlike in the microgame, the pins are always set up in standard bowling position rather than in different varities, and the player only has 2 balls to roll instead of 4 to knock down pins.
The standard bowling rules apply to this minigame. There are a total of 10 frames. If the player knocks down all the pins in one frame after using both balls, they will receive a spare. If they are able to knock down all the pins in one frame by using just one ball, it will result in a strike.
Additionally, there is a multiplayer option, in which the player can play with a friend and will take turns bowling. The person with the highest score after 10 rounds is the winner.
