When I mean “later”, it actually means in around 12 hours. One Piece: Moja! is the latest official mobile game based on the insanely popular anime/ manga, and only the Android version will be available, with the iOS version coming later in the summer. In Japan only, of course.
One Piece: Moja! is actually a game which contains 4 different mini-games, including Straw Hat Pinball, cards, a Zoro slashing game, and a battle/puzzle game. The app itself is free, with optional in-game purchases.
