Crazy Arcae (Korean: 크레이지 아케이드) is a free Korean online video game developed by Nexon. It used to offer five different game modes: Bomb and Bubbles (BnB) , Tetris, Hidden Catch, Dizzy Pang, and Bz. However, the latter four were soon 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.
