YOLO

From the publisher's website: YOLO is the addicting card game where the lowest score wins! Players are dealt four cards face down. Throughout the round you'll be swapping cards in and out trying to memorize which card is which number. The YOLO cards are the highest and lowest cards in the deck and can push your total into the stratosphere or save you! If you think your set of four cards is lower than everyone else's, then it is time to GO FOR IT! Why not? YOU ONLY LIVE ONCE!
