3 wishes
A not-so-nice-but-not-too-evil genie appears as if from nowhere (someone, somewhere probably did rub a lamp) and pitches the crowd against one another, granting the most astute player no fewer than three wishes — but not all wishes come true, and only the player with the right balance between super powers, benefits for the world, and selfish gifts will be enter the good graces of the genie.
In more detail, each player has a hand of three cards, with two extra cards face down in the middle of the gaming table. On their turn, each player can either peek at a card or swap cards with other players or the common pool on the table, aiming to get three different type of wish cards. Once that happens, someone calls for the end of the game and all players reveal their hands and compare wish cards to determine the winner.
