FAQ on the game - How many Pokémon in the game?
Remember the sensational in the 90s Pocket Monsters: Red & Green, released by Nintendo? So this was the beginning of a whole series of games involving Japanese cartoon monsters. Then they were, no more, no less than 151. With the release of each new game, the number of Pokémon was increasing, so today, according to Pokédex, we can count as many as 722 monsters. In the recently released Pokémon Go, not all Pokémon are involved, but the game is constantly being updated.
