Super Mario Run asks players to share their 12-digit friend codes in order to interact with players. Other options, such as linking Twitter and Facebook, are offered – but adding players to your friend list via player ID numbers is the default choice.

Super Mario Run is available now as a timed iOS exclusive. Be sure to check out our review to see what we thought of the new mobile game.
