In Dokkan Battle, the Dokkan wheel refers to a method, known as the Ki Glitch, that allows players to reboot the game to determine which character gains a Ki boost. The game also employs a currency system, where real money and credits are converted into Dragon Stones. These stones are used in Gachas or Summon Banners to obtain items, with the chance of acquiring rare to ultra rare items rising as more money is invested.
