Evolution is a process that many Pokémon can undergo, causing the Pokémon to change into a different Pokémon. This change in species is also accompanied by a change in the Pokémon appearance and a (usually positive) change in the Pokémon's base stats. The newly transformed Pokémon will also typically be able to learn moves that its previous form could not learn, although occasionally the Pokémon may lose access to certain level-up moves if they were not learned while in its previous form. Sometimes, the Pokémon may also have a different type than its previous form.

A Pokémon can evolve a maximum of two times, depending on what Pokémon it is. Some Pokémon may have the choice of evolving into multiple different Pokémon depending on the conditions that are met. Some Pokémon, including all Legendary Pokémon, do not evolve at all and have no evolutionary relatives.

Evolution can be cancelled by clicking 'Cancel' while the Pokémon is in the process of evolving. However, the Pokémon will try to evolve again the next time conditions are met. An Everstone can prevent the Pokémon that is holding it from trying to evolve.

In a bid to maintain the intimate nature of its sets, Aristocrat presents all its games with the same mode of play, which means one does not have to acquire a new set of skills to indulge in gameplay. The same method is spotted in the Sun and Moon slot machine, which is facilitated by the UI panel placed at the bottom of the screen. The only game in the casino is a slot machine-style game. Insert however many coins you want (1, 2 or 3, which add more rows on the slots where you can win prizes) and try and line up the same picture. A triple 7 yields 300 coins, three BAR yield 100 coins, three Poliwag, Diglett, or Jigglypuff win 15 coins, and three cherries earn 8 coins. The only game in the casino is a slot machine-style game.

Requirements

There are several different methods that can cause Pokémon to evolve.

Level

Leveling up triggers many evolutions, although another condition must be met upon leveling up for evolution to take place.

Specific level

The most common type of evolution is when a Pokémon evolves if they are at least a certain level upon level up. For example, Charmander will evolve into Charmeleon at level 16. If the evolution is cancelled, the Pokémon will attempt to evolve again on subsequent level-ups. The Pokémon evolved through this method will not be listed here as the list would be excessively long. The levels required for Pokémon to evolve can be found on each Pokémon's page.

Along with needing a specific level to evolve, certain evolutions can only take place if the Pokémon is a specific gender.

Evolution stones

Certain Pokémon evolve when certain evolution stones are used on them. The item will be used up as the evolution starts; if the evolution is canceled, the item will be wasted. Pokémon that evolve with evolution stones have very different level-up movepools than their evolutions, meaning that several moves may become unavailable for the Pokémon if evolved at a lower level, and other moves may be unavailable if evolved too late.
