Uno Junior Card Game
Players are dealt 5 cards, the rest forming a draw pile. The first card from the draw pile is turned over and players take turns matching the top card in the discard pile. Cards can match by number, color or animal. A player who can't match a card must draw from the draw pile. A player must call "UNO" once he is down to a single card. A player who fails to do so and is challenged by another player must draw 2 cards.
The first player to get rid of all his cards wins.
