I don't know what it's like everywhere else, but we play a game here that we call Euchre but it's really much more like Spades. I figured I'd throw out here to see if this is a regional thing or an Ironworker thing.

1. 4 players. You can play with 5 or 6, but that's more complicated and less fun. No partners, or "cutthroat."
2. The deck is only 10's through Aces, 20 cards.
3. It's a bidding/trick taking game, so each hand is made up of 5 rounds where whomever has the lead throws a card, and everyone else has to follow suit or can trump if they do can't follow suit (follow suit meaning if the first player throws a Heart, you have to play a Heart if you are able).
4. The part that confuses most people is in the trumps and scorekeeping. After the cards have been dealt, the players take turns bidding how many of the 5 tricks they think they can take if they get the lead. The winning bidder gets to decide what suit is trump *for that hand only*.
   1. The jack of the trump suit is the highest card that hand, often called the "right" or the "big"
   2. The other jack of the same color is the second highest card, aka "left" or "little."
   3. After the jacks, the value of the cards goes A, K, Q, 10 for the trump suit only. Every other suit plays at normal face value, aces high.
5. Once the winning bidder has called what suit is trump, players decide whether or not to play that hand, starting to the left of the winning bidder. A player can sit out three hands in a row, after which they are "in the box" and have to play the fourth hand.
6. Once all players have decided whether or not they are playing, the winning bidder plays his first card. Whomever wins the trick leads the next trick, and so on until all cards are played.
7. Everyone starts with 15 points. Every trick taken takes you down 1 point. If the bidder does not make his bid (does not take as many tricks as he called), he is "set" and goes up 5 points and gets a "hickey" (an asterisk on the scorecard). Every other player who participates in the hand needs only win one trick, but if they fail to get any, they are also "set," and go up 5 and get a hickey.
8. Whenever anyone reaches zero, everyone owes the winner a quarter for the game, and another quarter for every hickey earned during the game.

Does this sound familiar to anyone else? There are other more complex and detailed rules too but this is the broad strokes.
