ALGEBRIDGE Making the Deck: The deck consists of two parts

From "MATH NOTS, A Newsletter for Math Teachers," Ann Arbor, Michigan, Volume I, Number 2.
Making the Deck: The deck consists of two parts, playing cards and replacement
cards. The 52 playing cards can be 4 x 2.5 inch pieces of posterboard. The suits are
represented by 4 colors of felt pens. On each card print one of the following
algebraic expressions: (x2+3x), (x3-2x), (x2), (x3), (2x2-2x+2), (x4-x2+1), (x3+2), (7xx2), (x3+x2+1), (4x-x2), (x4-1), (1/2 x3), and (x3+7). These same expressions (or any
preferred ones) are repeated in each suit {color). The second part of the deck is a
set of 17 cards.
These are used to determine replacement value for x during play -- make 4 with numeral
4, 4 with 3, 4 with 2, 4 with 1 and 1 with 5. Shuffle well and keep separate from
playing cards.
Using the deck: The game is played like bridge. There are four players. The
replacement set is shuffled and placed face down in the center of the table. The
playing cards are dealt so that each player receives 13. The dealer turns over the top
replacement card -- this is the value by which to replace the variable for that trick.
The dealer now leads a card from any suit. All players must follow suit if they can or
if they cannot, they discard any card from their hand. (A card from the wrong suit
cannot win the trick.) The winner of the trick is the player whose card has the
highest value when replaced by the replacement value showing. It is now his turn to
turn over the next replacement card and lead. The winning team is the one that wins
the most tricks.
