Which variation of spades do you play? There are a bunch and it seemed to vary by household.
The one I grew up with, the trump cards are a little funky: remove the two of clubs and two of hearts and replace them with the big and little joker, which become the two highest spades. Then the two of diamonds becomes third highest spade, the two of spades is the fourth highest, then ace and king on down. If you make two or more books than what you bid, you get your bid subtracted from your score. Bidding and making a ten book hand is worth two hundred points. Blind bids are worth double.
Sometimes the first hand bid's itself, so whatever you make is what goes on the scoreboard.
Rarely: Before bidding, allow passing one or two spades to your partner in exchange for their weakest cards, but only if those are your only two spades.
Some people play with shitty additional rules to speed up the pace like:
Ace Check - asking your partner how many aces they have and if you have all four between the two of you and you make them all you get an additional hundred points.
Top Five - same thing, but with the top five spades
First Seven - make the first seven books in a hand, extra hundred points
Bid and make all 13 books - game over
