The latest in the Rumble series will be free to play on 3DS and include over 700 Pokémon.
Pokémon Rumble World is coming to the 3DS eShop on April 8 for free.
This free-to-play entry in the Rumble series, which last appeared on Wii U in 2013, lets you play as over 700 Pokémon, including some mega ones. You use Pokédiamonds to get new balloons, which carry you to new environments. You can get diamonds by StreetPassing, completing objectives in the game, and spending your own hard-earned money.
