Slot machines for enabling team play by a plurality of slot machine players are disclosed. The game results of each team player are combined in a predefined manner to obtain a team game result. The game results of each player may be combined on a "per-spin" basis, or collected for each team player over an entire play session, with the net result of each team player combined on a "per-session" basis. In a "per-spin" embodiment, each team player initiates play, and the individual game results of each team player are combined in a predefined manner to obtain the best team game result, with the highest resulting payout, for each spin. In a "per-session" embodiment each team player continues play for an entire play session, and the net result of each team player is analyzed in a predefined manner on a "per-session" basis to obtain the team session result. A session can be defined, for example, in terms of (i) the number of plays per session; (ii) the duration of the session; or (iii) all plays until a predefined event occurs.
