The BallLocke variant of the Nuzlocke challenge is played with standard Nuzlocke rules, with one major addition: the player may only catch one Pokémon in each type of Poké Ball. For example, the starter Pokémon comes in a standard Poké Ball, so the player may catch another Pokémon in a Great Ball once they have access to one, then one in an Ultra Ball, and so on. This challenge adds a great degree of limitation to earlier Pokémon games with less types of Poké Balls, but presents an interesting challenge even in later generations.
