The Dizzy series of computer games, published by Codemasters, was one of the most successful European computer game brands of the late 1980s. The games featured a central figure: an intelligent egg-like creature called Dizzy. The games would typically involve Dizzy trying to save his friends and family, the Yolkfolk, often from the schemes of his nemesis, the evil wizard Zaks.
Most of the games in the series were platform games, with an emphasis on puzzle solving, similar to graphic adventures. Dizzy would roam around various fairytale-like locations, collecting objects, interacting with other characters, and solving logical puzzles. Rather than jumping in the conventional platform-game way, Dizzy would somersault and roll around the landscape; hence the name "Dizzy". The eight games which follow this style, usually referred to as the arcade adventures, are considered the 'core' games in the series; however, several spin-off titles were released, including Fast Food, Kwik Snax and Dizzy Down the Rapids.
Four games in the series were included in the Top 50 best games of all time in a special issue of Your Sinclair magazine in 2004.
Dizzy was created by the Oliver Twins (who later formed Interactive Studios). The Oliver Twins left the series after Fantasy World Dizzy, and the remaining games were developed by Big Red Software.
The first game in the series, called Dizzy - The Ultimate Cartoon Adventure, was released in June 1987. At this point, Dizzy was not specifically intended to be an egg; the shape had been chosen because it was easy to rotate and animate. The Yolkfolk characters were not introduced until the third game, Fantasy World Dizzy.
