We have the tiniest twist on this - the person holding the last card, in our house, is the winner - IF they can say what the missing card is going to be before they look at it. If you have a couple of "sore losers" in the house, it's a friendlier ending.

Really? That is SOOOO not how we were doing it, LOL! I read it as mix up the cards, divvy them up, then make matches of 10, then start picking other player's cards!
