Poker is a card game that can be played for money. The object of the game is to have the best hand, or to convince other players to fold their hands, so that you can win the pot. There are many different ways to make money from poker, but the most common way is to play in tournaments or cash games.
Tournaments are poker events where players pay a buy-in to enter, and the prize pool is distributed to the top finishers. Cash games are poker games where players can buy in and cash out at any time, and the pot is won by the player with the best hand at the end of each hand.
