Poker tournaments and cash games are two different formats of poker. There are a few key differences between the two:

Buy-in: In a poker tournament, players pay a fixed buy-in to enter the tournament. This buy-in is used to create the prize pool, which is distributed to the top finishers. In a cash game, the chips have the exact same value as the respective currency (ex: Dolar) and players buy chips at the table and can buy more at any time, up to the table maximum.

Chips: In a poker tournament, players are given a certain number of chips when they start, and their goal is to eliminate other players and accumulate all of the chips in play. In a cash game, players can buy in for any amount up to the table maximum and can leave the game at any time, cashing out their chips for real money.

Blinds: In a poker tournament, the blinds (forced bets made by certain players before the cards are dealt) increase at regular intervals, usually every 15-20 minutes. This is done to encourage players to play more aggressively and eliminate other players. In a cash game, the blinds remain the same throughout the game.

Structure: Poker tournaments have a set structure, with a fixed number of players and a predetermined payout structure. The last remaining player is the winner. In a cash game, players can come and go as they please and there is no set end to the game.

Both poker tournaments and cash games can be played in a variety of poker variants, including Texas Hold’em, Omaha, and Seven Card Stud.
