I haven't played it for a couple of month, but when I was playing regularly it went like this:
One person, the one who won the last round, gets to hide a real object in their home, that is, physically take a thing out of its normal place and put it somewhere else. The rest of us get to use our Tarot decks to work out two things: what the object is, and where it has been placed.
Me, I found one particular deck to be very good at it. I'd pull two cards, one for "what" and one for "where". And I wouldn't think about the meaning of the cards at all, but I'd look at details: the kinds of scenes, objects shown in the card, and occasionally the meaning. Then we'd write our thoughts back, and hte person who had hidden the object would say "warm" or "cool" to indicate if we were heading in the right direction.
After playing that game for a while, it takes fewer and fewer guesses, especially with decks that don 't mind a bit of casual fun. A while after I stopped playing (for want of time, not because I wasn't interested), someone here PMed me in great distress, having lost their grandmother's necklace. I pulled a where card only, since I already knew what, and they looked where I suggested, and drew a blank. So I pulled another card, and bearing in mind the previous card as well as the new ones, suggested some other stuff. The necklace was found.
More recently, a friend of mine who's only dimly Tarot-aware and certainly isn't Aeclectic-aware, lost her car-keys, and because she and her partner were at war, needed to find them again before he found out. I pulled the Star. I couldn't think of anything except "look in the place you most often go in the early evening". She found the key-ring stuffed under the cushions of the lounge where she liked to sit and watch the news of an evening. That was on a first guess.
That game is *very* good at getting you in-tune with how your deck communicates ordinary stuff, something none of us should ever be high-and-mighty enough to ignore.
ohhh this sounds like fun, i hate that i was in a rush this morning and forgot everything! including my deck!!!!
