Players must kill their opponents by setting water balloons that pop and release water both vertically and horizontally. Being exposed to the water causes characters to become trapped in a bubble. If a teammate makes contact with a trapped player, the player is released from the bubble. If an opponent does the same, however, or if the player does not make any contact within a short period of time, the player dies, which may or may not remove the player from play, depending on the mode of gameplay.
