There are many different types of poker tournaments. The variety is limited
only by the imagination of the casino. While poker tournaments are for poker
players, every casino game generates its own tournaments for the players who
most like those games.
Many poker tournaments have a buy-in, but some, like freeroll tournaments don't. The dollar value of a player's chips are a kind of fiction. The winner is usually the one who garners all the chips in the entire tournament. At many tournaments, every player who makes it to the last table wins money.
A tournament can involve as few as two players up to thousands. When you peruse online casinos, you will find tournaments scheduled to start around the clock.
