A loser may have to serve (by voluntary pre-agreement) as a “slave” to a winner for several days. A winner may be rewarded by ten free minutes of electronic pleasure-probing of his brain. A player may risk flogging or its psychological equivalent—participation in a day-long session during which winners are permitted to work off their aggressions and hostilities by sneering, shouting at, reviling, or otherwise attacking the ego of the loser.
