Kids love wild cards, and Crazy Eights has them in droves.
Deal seven cards to each player. The rest of the deck goes facedown in a pile, with the top card turned up beside it forming the discard pile. (If the card is an eight, put it back and turn up the next card.)
The player to the left of the dealer discards a card from his hand that matches either the suit or the rank of the top card in the discard pile. If he has no such card, he picks up cards from the deck until he gets one that's playable.
Play continues in this fashion, with players matching the card at the top of the discard pile. Eights are wild and can be put down on any card. The player who discards an eight chooses the suit his opponents must play next. A player may pick up from the deck if he has a playable card in order to change the suit to one he suspects the next player does not have, forcing her to pick up cards.
The first player to use up all his cards wins.
