Free Battle: A number of battles is given freely when starting each stage.
Play Again: when you run out of free battles, the participant will spend a certain amount of tickets to use Play Again for more battles in the same stage.
Play Again will be used only in the game Thetan Rivals.
The number of tickets required will increase with each use of "Play Again" within the same stage.
The number of required tickets for Play Again will be reset after the stage ends.
