The game box itself is used as a 3D board, divided into four areas separated with ricocheting barriers and containing a big hole in the center. The players attempt to flick their fleas (chips) onto the board tiddlywinks-style, with the goal of having the most chips in each area, but without having them fall in the center hole. Players with good dexterity can attempt to use their chips to knock other player’s chips out of an area and, preferably, into the hole. There are special chips that freeze out (or neutralize) an area, as well as other special chips that serve to neutralize the neutralizing chips.
