How do you get invited into realms? Does someone from mojong have to invite you? If they do invite you do you have to pay? And finally is realms local or online? I am able to play regular multiplayer though.
I have Realms, I live in Sweden but people from all over the world can play on the server once I've invited them.
It's free to play. You only need the invitation (the Realms owner has to know your game name to be able to send you an invitation), other than that it works pretty much the same as regular servers. The game it self is the same.
Minecraft Realms is currently avaivable only in sweden. This is not a free service, the Realms server costs a little if you want to host your own. If your friends might have bought a realms server, they can invite you to play.
