Oh, Hell, Culver City Style

Game: 13 hands.
Deal: 4/player on the first hand, increasing by one until
      the last four hands, which are played with 13 cards.

High bidder names trump.  Notrump is allowed.

Scoring: 
    Make	Score
     0            5
     1            6
     2            8
     3           11
     4           15
    more        (n-1)*5

Undertricks or Overtricks are -5/trick, unless
the high bidder has outbid a 5-(or more)-bidder, 
in which case the 2nd and subsequent *undertricks*
are -15 each.

Even bids are disallowed.

---------------------------------

Matt Ginsberg plays this version (I quote verbatim):

First deal has 52/n cards, then down to 1, then 1 again, then up to
52/n (n players).

Face a card to determine trumps (if whole deck in play, face a card
before or from other deck).  Q/J = no trumps, otherwise, trumps = suit
of faced card.

Person to left of dealer bids first and leads.  Bid number of tricks
you expect to take.  Final bidder can't make it come out "right".

Score:  If correct, get 10 + bid * bid.  If wrong, lose the cube
of your error.

With 5 cards or fewer, whoever is winning has to bid last.  In event of
a tie for first, final bidder is whoever bid last least recently.
