The game is only playable on New 3DS systems (New 3DS, New 3DS XL, New 2DS XL). It will not feature online multiplayer but the developers are working to bring local multiplayer in a future update.
Here's the official description from Nintendo:
Create. Explore. Survive.
Minecraft is a game about placing blocks and going on adventures.
Explore randomly‐generated worlds and build amazing things from the simplest of homes to the grandest of castles. Play in Creative Mode with unlimited resources or mine deep into the world in survival mode, crafting weapons and armor to fend off the dangerous mobs.
Create and explore your very own world where the only limit is what you can imagine. Includes five skin packs and two texture packs to customize your gameplay! Use the touch screen to check your map or manage your inventory!
As always, please coordinate with your preferred branch first to avoid unnecessary mishaps. You can use the Game Retailer Branches & Contacts page as reference for store locations and contact numbers.
