Lucktails is a baiting game of inconceivable chances.
You can flip over the one card that you have been dealt. You can also switch it out for one of the two cards in the middle of the table and flip that card over instead. Either way you get the flipped card's victory points and immediately drop out of the current round. However, since you must not look at any of these cards before the flip it is often smart to try to bait other players into dropping out before you. With a bit of luck their flipped cards will provide you with valuable information.
