This trick-taking game is a standard deck playing card game and takes on many different group-specific rules. Generally speaking, each player is given thirteen cards and a partner who sits across the table. Each player bids the number of tricks he'll take, and then the partners collectively attempt to take at least as many as they bid. The tricks are fairly standard with following suit if you can, and spades as the trump suit. If you make your bid you earn ten times the number of tricks you bid, otherwise you lose that many points. Plus there is usually a nil bid, which means you personally won't take any tricks but your partner still plays as normal.
Very nice, official-looking, easy to use. There is a very helpful example sheet (page 1 of 3). Made for easy front-and-back printing. Page 2 is pre-prepared for up to twelve hands--usually enough for a standard game to 500. But some people might want to just print out multiples of Page 3, which has 11 rows (hands) and is more of a blank slate; it can be used for the beginning of a game and also as continuation sheets.
