The randomizer can be used to create new challenges for experienced players, or to introduce new players to the game.

Players now have the opportunity to change up their game play in a variety of ways. The first randomizers were created in 2010 for the video game series Pokémon Black and White. A universal Pokémon randomizer is a computer program that shuffles the order of all 718 Pokémon in the National Pokédex, making it possible to get any combination of Pokémon in any game.
