This is probably one of the finest party games ever made. Simple to learn, and you can even play it after you've downed a few "beverages". In fact, many contend that their skill at this game is enhanced after consuming said spirits prior to or during play.
Whatever your fancy, Apples to Apples is a winner. Here's how it works:
First off the game requires at least 4 players. In fact, the more the better. There are two types of cards in the game - Red Apple Cards and Green Apple Cards. Each player is given a set amount of Red Apple Cards for their hand. These cards are kept secret from the other players. Red apple cards generally have a noun printed on them - people, places, things, etc. Then, one player sets their Red cards aside and becomes the judge. The judge draws a single Green Apple Card. Green cards normally have an adjective on them but not always.
When the judge has drawn the green card, he/she lays it face up in the middle of the table. The other players then play red cards face down (there is a limit on how many can be played depending on how many people are playing) on the table. The judge then reviews the red cards in secret and the one he/she determines best fits the word on the green card wins the hand. The player who's card was selected then takes the green card. Red cards are redistributed and the judge player is moved to the left. The first player to collect a certain number of green cards wins.
Keep in mind that the most red card played that is most ACCURATELY described by the green card is not always selected - it's all about what the judge thinks. Hence, my friends call this game "Know Thy Judge" (which has since morphed into "Know Thy Apple"...but that's another story). For example, my father-in-law is a die hard Chicago Bulls fan (it's really his only shortcoming). One of the red apple cards says "Michael Jordan". Regardless of what the green apple card is, if he's the judge and you play that red apple card - you win. Does this make sense? No. But does it make the game light and very fun? Oh yeah!
This is a game not to be taken seriously. So don't try. Hence, it makes a great party game. Sit back, relax and listen to people start to laugh and have a great time.
