In Ghost Wiper, players are tasked with clearing a room of ghosts by absorbing them with a small, circular pad. The player controls a cursor that can move a miniature paddle to absorb the ghosts.
The main challenge lies in navigating the room without colliding with the ghosts or other obstacles, all while avoiding bumping the cursor into the edges of the screen. The game runs in a web-based environment, requiring no download or registration to play.
