Carnival is a fixed shooter arcade game created by Sega in 1980. It has the distinction of being the first video game with a bonus round.
The goal of the game is to shoot at targets, while carefully avoiding running out of bullets. Three rows of targets scroll across the screen in alternating directions; these include rabbits, ducks, owls, and extra-bullet targets, with higher rows awarding more points. If a duck reaches the bottom row without being shot, it will come to life and begin flying down toward the player. Any ducks that reach the bottom of the screen in this manner will eat some of the player’s bullets. A large pop-up target above the top row can either award or subtract bullets or points when hit. A spinning wheel with eight pipes also sits above the top row; these pipes and all targets must be shot in order to complete the round. In addition, a bonus counter increases by the value of every target shot in the three rows. The letters of the word “BONUS” are scattered among the targets; shooting these in order awards the points. The bonus stops increasing as soon as any letter is shot.
At the end of each round, the player receives bonus points for all unused bullets, then plays a bonus round in which a large bear with a target walks across the screen. Each time the bear is shot, it rears up for a second, then begins walking more quickly in the other direction. The object is to shoot the bear as many times as possible until it escapes off the screen. Following the bonus round, the next wave begins. Later bonus rounds add more bears to the screen.
In higher levels, there are more ducks and fewer extra-bullet targets, putting a premium on accurate shooting. The game ends when the player runs out of bullets.
The tune that plays throughout the game is Sobre las Olas (Over the Waves) by Juventino Rosas, a tune commonly associated with carnivals and funfairs.
Carnival achieved enough popularity in the arcade that it was eventually ported to all three of the major home video game console systems of its time. There were also unofficial clones for home Microcomputers such as Acornsoft’s Carousel.
