After the bidding is complete, the game begins. The player who won the bidding leads the first trick. The other players must follow suit. If a player does not have any cards of the same suit as the lead card, they can play any card they want. The highest card of the suit led wins the trick, unless a player plays a spade. Spades are always trump, which means they beat any other suit. The player who wins the trick leads the next one. The game continues until all 13 tricks have been played.

After all the tricks have been played, the scores are tallied. If the team that won the bidding took the number of tricks they bid, they receive 10 points for each trick. If they did not take as many tricks as they bid, they lose 10 points for each trick they were short. The other team receives one point for each trick they took.

Multiplayer Mode: In multiplayer mode, you can play with up to three other people. You can either join a game that somebody else has created or create a game yourself. When you create a game, you can choose the number of players, the bidding system, and the maximum score.

Tips and Tricks:

1. Pay attention to which cards have been played. This will help you predict which cards your opponents might have.

2. Try to avoid taking tricks with low cards, especially if they are not spades. You want to save your high cards for when you need them.

3. Watch your opponent's bidding. If they consistently overbid or underbid, you can adjust your bidding strategy accordingly.

4. Remember that spades are trump. Try to save your spades for when you really need them.

5. Don't be afraid to go for a nil bid (zero tricks). If you successfully take no tricks, your team gets 100 points.

Overall, Spades: Classic Card Game is a fun and challenging game that is easy to learn and difficult to master. With practice, you can become a skilled Spades player and impress your friends with your card-playing abilities.
