Raise and chance is not just lotteries, horse races and bingo, but it is whichever situation that involves a gamble and the luck factor: both aspects are presented in the ludic love-sexual discourse, from graffiti collected in male and female restrooms of University of Zulia (Maracaibo, Venezuela). The objectives are: 1) Determining the presence of raise and chance in these graffiti; and 2) building the communication model that underlies this "doing". This research is focused under the spatial semiotics perspective (Greimas et Courtes, 1979; Auge, 1996; Landowski, 1997). Nine ludic-thematic areas, of which the sexual gambling (32%) predominated, were gotten. This allowed building the ludic-sexual communication model, where a mediate dialog between an offerer gambler and a demander chance gambler, who gamble to sex, is established. Furthermore, man addresses his message-gamble to the same sex gamblers and women have broken the barriers of a "doing" that it was considered as something exclusive of men.
