To play dirty dice, all players place a wrapped gift into a pile and then take turns trying to roll a pair so they can grab a gift. Once there are only two people left without gifts, they take turns trying to roll a pair. Once someone rolls a pair, he selects the second to last gift and the last player takes the last gift available.
In the second round of the game, a buzzer is set to 10 or 15 minutes. The last person to get a gift gets to roll the dice first. If he rolls a pair during anyone else's turns, he gets to trade his gift with someone else. If another player rolls a pair of sixes, then that person gets to trade his gift for someone else's, but nobody can take his gift from that point forward. Once the buzzer sounds, the players get to unwrap their gifts and see what they got.
