Mega Evolution/Other Games/Pokémon Shuffle

Before a Pokémon's Mega Evolution can be used in Pokémon Shuffle, its respective Mega Stone must be obtained (or in 's case, the Meteorite), typically either by defeating its Mega-Evolved form in a battle at the end of each  or as a prize for completing a Competitive Stage or reaching a certain point in an Escalation Battle.

The Pokémon placed in the first position (furthest to the left) when selecting will Mega Evolve after the player fills the Mega Gauge by matching the Pokémon being Mega Evolved or matching Pokémon with the Mega Boost(+) Skills who are of the same type as the Pokémon being Mega Evolved. The size of the Mega Gauge depends on the Pokémon being Mega Evolved, with each Pokémon requiring different numbers of icons to be matched to fill its gauge. The Mega Effects for each Mega form vary between Pokémon, replacing the Pokémon's Skill for the remainder of the battle.
