Pokémon is one of the most popular franchises in the world, and its anime and video game series have been running for decades. The creature-collector has inspired many games because it’s easy to learn but hard to master, giving it the perfect difficulty curve.

The concept is simple: find a Pokémon in the wild and beat it until it’s almost unconscious. Then, trainers can pelt the Pokémon with Pokéballs until they catch it. You can then raise the Pokémon and make it stronger by having it fight other wild or caught Pokémon until they faint. You lose if all of your Pokémon faint during battle. But if you win, you get money.
