How do you play spades with 4 players and what are the rules of the game?

In a game of spades with 4 players, each player is dealt 13 cards. The objective is to win as many tricks as possible by playing the highest card in each round. Spades are the trump suit, meaning they outrank all other suits. Players must follow suit if possible, but can play a spade to win a trick if they don't have the suit led. The team that wins the most tricks wins the round. The game is typically played to a set number of points, with points earned by winning tricks as predicted before the round.
