Carnivals are contests where Pandora are pitted against each other to determine their ranking of strength. Limiters do not take part in them. There is a Carnival each season at all Genetics academies to determine the strength rankings of cadet Pandora's in their class years, underhanded tactics may be used and killing is also allowed. Every few years, there is a worldwide cadet Carnival for the students of the various Genetics academies to determine the world rankings.
In Freezing: First Chronicle, it it stated that Genetics take footage of each Carnival.
Carnivals are a point-based duel system. A Pandora earns five points by being able to deploy their Volt Weapon. When Pandora are locked in combat, they earn points at the start of the battle. The winner earns a bonus for winning a duel and then she earns additional points equal to ten percent of her opponent's current points. This system maximizes a Pandora's combat experience by encouraging them to battle one another and incentives them to battle stronger opponents no one Pandora can get too far ahead. In addition, Pandora may exponentially earn points based on their number of consecutive victories.
Despite the effectiveness of this system, it can be easily "cheated" by wise, strategic Pandora, such as Elizabeth Mably, who allowed her enemies to earn a lot of points before she defeated them after they had been weakened. This way she racked up more points by defeating Pandora who already had a significant amount of points. Elizabeth's strategy led her to earn first place in her first Carnival by defeating only four Pandora.
