Pokémon Pokopia lets you play with up to three other people in multiplayer.
That means a host can share the town with three additional players, creating a maximum group of four people. The official description highlights visiting friends’ towns, inviting friends to your own, playing games such as hide-and-seek, and working together on large building projects.
The wording matters because “three other people” is not the same as “three players total.” The host is included in the total group, so the maximum number of simultaneous participants is four when the host and three visitors are counted together.
Pokopia’s multiplayer features complement its solo building systems rather than replacing them. Players can still gather resources, construct habitats, and develop their own town alone. Multiplayer adds shared visits, cooperative construction, and social mini-games to the life-simulation experience.
