Millions have already picked up Pokémon Sun and Moon and are exploring all the new features the games have to offer. One such new experience, Global Events, are opening up today with the games’ first worldwide challenge.
The first task for gamers around the world is rather straightforward: capture a combined 100 million Pokémon. That may seem like a large amount but remember, the game has already sold many millions of copies. In order to participate there are a few steps you’ll have to follow. First you’ll want to make sure you have visited the Festival Plaza and activated Game Sync. Once this is accomplished you can accept the mission, also in the Festival Plaza.

If the mission is accomplished, every participant will receive 1000 Festival Coins; if not, then they’ll still receive 100 Coins for the effort.
