Crazy Arcade (Korean: 크레이지 아케이드) is a free Korean online multiplayer game developed by Nexon. It has offered up to five different game modes throughout its history: Bomb and Bubbles (BnB), Tetris, Hidden Catch, Dizzy Pang, and Bz. However, the latter four were eventually removed from the game. BnB, which takes on the classic Bomberman series, adds its own twist to the game by replacing Bomberman's bombs with water balloons. Crazy Arcade's success spawned a franchise, having been followed by the release of the games CrazyRacing KartRider, CrazyShooting BubbleFighter, and CrazyRacing AirRider. Nexon announced that they will be bringing Crazy Arcade, as well as Dragon Nest and Mabinogi Heroes to America in 2010 under their new game portal, Block Party. On December 7, 2009, Nexon America launched the official website for PopTag!, which is the North American name of Crazy Arcade. Nexon has decided to forgo the closed beta testing phase and jump right into an open beta. The open beta of PopTag! began on January 26 and ended a month later. PopTag! was closed by publishers Nexon America on July 14, 2011 due to "multiple factors including the [in]ability to deliver new content regularly due to the limited resources [...] available for the game". Gameplay 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. Up to eight people can battle in a room either by Manner or Free mode. But in other cases, there is a limit. For example, in Village 10, there can only be six people at a time, as there is no more room to spawn in that area. In Manner mode, teams are evenly divided by color. Free mode allows teams to be arranged in any way that suits the players. Experience points are awarded for completing a match, more for a victory than a draw which gives more experience points than a loss, and gaining enough points will result in a level-up.
