StreetPass is a feature that is built in to the Nintendo 3DS system. With this feature, when you pass other players while your console is hibernating, it will share data with them on the fly. Pokémon Rumble World uses this feature to collect various other Mii players. When you first pass the players, you will have to rescue their Mii during a small mission. Then, these Mii players will show up as you play and can offer you a variety of bonuses.

• X Attack: Boosts the Attack of your Pokémon
• X Defense: Boosts the Defense of your Pokémon
• X Speed: Boosts the Speed of your Pokémon
• Potion: Heals your Pokémon

You may also receive a PokéDiamond from them.

The game also uses the SpotPass feature of the Nintendo 3DS. This feature will bring various other players from the Internet into your overall plaza. Once a day, you can connect to SpotPass and download up to three of your friends. They will appear in the plaza and willalso require rescuing from stages.

In addition to that, if you have spent your free attempt at calling people in, you may spend 10 Play Coins to bring in more people.

When you have received other players from the game, you can check them in the Adventurers Tab on the touch screen when in the hub. From there, you can check their specific stats for the game including playtime, Pokémon caught etc., as well as mark favourites and view the photo they captured with their Pokémon.

You also have the ability to check each player's stats and sort by them in order to fully get as much detail about that player.

With the StreetPass and SpotPass features, you will also receive PokéDiamonds for free when you achieve certain milestones for it. This includes both StreetPass and SpotPass features. Each PokéDiamond batch can be redeemed just once.
