Zeny or Bayong is a tradition in Ragnarok Online events. It's patterned after the hit segment on TV, Pera or Bayong. Zeny is the currency in Ragnarok Online. The winner of this side event is a lucky girl named Ayan from Valkyrie server.
She just became 4 billion zeny richer in-game (or was it 400 billion?). That's a HUGE amount of money (zeny) in-game.
Here are the pictures of the participants of the Zeny or Bayong Contest at the Skydome, SM North EDSA, in celebration of the 10th Year Anniversary of Ragnarok Online in the Philippines.
