Bought this game after I saw it played on a South Korean game show, of all things. The rules are very simple: a card is drawn and, taking it in turns, you either put a chip on the card, or take the card and all the chips. If you have a run of cards, only the number on the lowest card counts. At the end of the game, add up the numbers on your cards, subtract 1 point for each chip left and whoever has the lowest score wins.
The play time is short, but the game turns out to be surprisingly complex. I've spent whole evenings playing this, watching players "level up" as they add new techniques to their toolbox. Should you take the card you want, or send it round hoping to get more chips? Maybe someone else will take it? How many chips are the top cards worth? I still have no idea what the best strategy is. Thoroughly recommend it!
