The first game featured portrait ghosts that the player would have to defeat by exposing their heart through a certain method, whereas the third game has Boss Ghosts that are similarly required to be defeated through certain methods. This was used for puzzles and secret areas. From the second game onwards players use the Strobulb to stun ghosts and then proceed to suck them up, but also a device known as the Dark-Light Device that would reveal objects that were hidden by spirit balls. In the first game, the player would have to use the flashlight to stun ghosts' hearts once they were exposed. The player uses Luigi's Poltergust to stun and vacuum up ghosts. The gameplay revolves around Luigi exploring various haunted locations solving puzzles and defeating ghosts. Various ghosts from the first game, as depicted in the remake
