Card Game- Who are you?

This is a simple and hillarious game, it has so many versions, so i'll write down the basic version.

Divide the cards equally among the players (use 2 packs if many). Each pile must be face down, and on the table. Now, everybody selects a name from the group, meaning at the end, each player must have a name that's not theirs.

Ok, it starts with the first person opening their card in front of their pile, and everybody takes their turn opening, one by one. Anyone with the same card, shouts the other person new name.
The first one who shouts the correct answer, hands over the pile of open cards in front of him to the loser.

haha..it gets a little confusing after a while, but lots of fun. The winner is the one who finishes his pile first.
