This is an idea I've had for a while, but I haven't hammered out any flaws yet. It's not exactly a card game, in the strict sense of the term, but it does merit sharing:
For three people or more; I recommend 3-5. More than that, and the game is probably going to be agonizingly boring.
Contents: special PYL cards, including $$, $$+spins, prizes, "directional spaces" (the `Move 1 Space, Pick-a-Corner, etc.) and, of course, Whammies; "Big Board" template, with numbered spaces 1-18; spinner (or die, or whatever); question cards; 15-second timer; instructions (duh!).
To setup: Deal 18 cards, one on each space on the Big Board template, and set the rest of the cards aside. This becomes the "Big Board" for the game. (Only one round is recommended, for purposes of time. If more rounds are played, simply collect the cards after each round, shuffle, and redeal.)
Play: Select an emcee. Said emcee will draw a question card from the deck and read it to the player on his left. The cards will be Family Feud-style ("Name a..."). Immediately after the emcee finishes, the timer is flipped, and the player will attempt to rattle off as many answers as possible. Each answer that fits the question equals one spin on the Big Board. The emcee position passes to the left, and so does the player answering questions. Repeat this process until everyone has had a chance to answer a question. The emcee position subsequently ceases, as it is no longer needed.
NOTE: As an alternative, the individual questioning can be thrown out, and instead do the questions with everybody at once. The emcee position still rotates, to give everyone a fair shot. (In this case, however, the questions will have to have a correct answer and two multiple-choice answers not open-ended as in Family Feud. A correct answer earns you three spins and a correct multiple-choice answer gets you one spin.)
However, I tend to favor the first set of rules, for two reasons:
1) It ensures that there are no arguments over who answered first, and
2) It ensures that everybody gets at least one spin, and thus nobody hogs all the spins.
Anyways, now it is time to face the Big Board.
Whoever has the most spins will go first. Spin the spinner. Whatever number the spinner stops on corresponds to a space on the Big Board. (At this point there are two options: either 1) collect the card and keep it in front of you, replacing the cards as they are removed, or 2) simply record the result on paper, leaving the cards where they are. I favor the former for two reasons: 1) It helps to have a stack of cash cards in front of you, instead of numbers on paper, and 2) the Big Board will change, like it does on the show.) If a Whammy is hit, the player must discard all cash and prizes he accumulated up to that point. At any point during the game, a player can pass his leftover spins, as in the show. They will go to the player with the highest cash amount at the time. Play stops, and the player on the receiving end of those spins will play immediately. If a Whammy is hit, the rest of the spins turn into earned spins and the player is then free to do with them what he wishes. As always, four Whammies eliminates a player from the game. He must return all cards, Whammies included, to the discard pile and withdraw from the game. Said player may now weep quietly.
After all spins have been used, count up the cash and prizes. Whoever has the highest total is the Press Your Luck champion!
So there you have it. Constructive criticism is always accepted and encouraged!
