There’s 18 different types of Pokémon, and each type is either strong, weak or neutral to other types. The guide below is a basic breakdown of who is better against each type.
While knowing which Pokémon is of what type is the basics of battling and winning you also need to know what ability each Pokémon has and how to counter it. So for instance if you have a Growlithe it is classified as a fire Pokémon but his standard attack is “bite,” which is classified as dark. So the Growlithe will be vulnerable to water as a fire Pokémon, but he’s only going to get a fire bonus for attacking while using his special attack, flamethrower. It’s a bit complicated, so get to know a few of your Pokémon well and make sure you’re keeping a well-mixed bench because you can bring up to 6 Pokémon to battle at once.
