Games: Higher or lower

Call it right and you score 50 points; every 100 points he drops a layer. Call it wrong and it costs you 25 — slip back under the line and he puts it back on. Five wrong calls and he's dressed and gone. Aces are low. On an ace or a king the deck can turn up a joker: the joker always wins, and is then replaced with a card from the deck. Clear him all the way to the last shot to win, then a new guy steps up.
