Summarize the following:
The player who declared the bid will “lead” by laying down a single card. Then, the other players will play one of their own cards in turn. The player with the most valuable card wins the trick. After the trick, each player should grab a new card from the stock to replenish their hand.  A lead in the trump suit automatically wins the trick unless another player lays down a higher card of the same suit. If the lead card is of a different suit, the other player must play a higher card or a trump in order to be victorious. Players must follow suit or play the highest card in their hand if they can. However, you don’t have any cards of the right suit or ranking, you’re free to play any card you like. The winner of the first trick should collect all four cards and put them into a separate stack face down on the table in front of them to be scored later on. This player will then lead the next trick. Update the score card after every trick you complete, awarding points only for “counters” (aces, tens and kings), which are worth 10 points apiece.  If the trump suit is diamonds and the lead is a ten of hearts, a player who lays down a jack of diamonds will come out on top.  The points you accumulate for laying melds will be added to your score when the game is over. Proceed in this fashion, with the winner of a trick leading and the other players attempting to match or beat their card. Winning the 12th trick will earn you an extra 10 points, so be sure to include those in your total.  The highest possible score you can be awarded for taking tricks is 250—240 points for the 24 counters and 10 bonus points for winning the final trick.  The more tricks you take, the better your chances of winning the game. Once all 12 tricks have been taken, tally up the counters each player has collected. Any melds they have down will be added to that number to give their final score. The player with the highest score wins the game!  If a player fails to meet their declared bid, the bid will be subtracted from their score.  Each deal is one game. When a game ends, gather all the cards together and shuffle them before you begin a new one.

Summary:
Lead a card for the first trick. Pull the winning cards from the trick. Continue until you’ve played 12 tricks. Total each player’s score.
