Pigs in Space comprises of three mini-games, which are selected from the game choice screen.
When players complete a single round of any game, they return to the game choice screen. They can select a new game or a game they have already played. Each time they select a game in which they have already completed a round, they are given a more difficult round to play. Difficulty switch must be set to the B position. In this setting, players earn a bonus round every 10,000 points.
