In addition to being able to offer higher "kakuhen" percentages, "koatari" made it possible for manufacturers to design battle-type machines. Unlike old-fashioned pachinko machines that offer a full payout or a "kakuhen" for any type of jackpot earned, these machines require players to hit a "kakuhen" jackpot with a certain probability in order to get a full payout. This is orchestrated by the player entering into "battle", where the player, in accordance with the item that machine is based on, must "defeat" a certain enemy or foe in order to earn another "kakuhen". If the player loses, it means that a normal "koatari" has been hit and the machine enters into jitan mode.
