A new event is underway in Super Mario Run and it is a blast from the past.
It was back in December iOS owners got to first experience the event and while we bid it farewell about a month ago, the Friendly Run Event has run its way back to Super Mario Run! Official description and details of the event can be seen right here:
Since this event has made a return though, I can’t help but hope the Coin Event will also make a return. After all, you can never have enough Gold Coins.
