When it comes to casino terms, action can have multiple meanings. Depending on the casino game you’re playing, action may either refer to the total amount of money put into play by you, or by everyone else at the table.
In addition, regardless of the game you’re playing, action can also mean that it is your turn to make a move. For example, when you’re sitting at a table that has multiple players (a poker table, for example), the action is often passed from one player to another in a clockwise direction.
Therefore, you shouldn’t be confused if you are playing poker and the dealer says that the action is on you because it simply means you should decide whether you want to fold, call, raise, or check so that you can pass the action to the player on your left.
Keep in mind that after each player takes action, it will be up to you to decide on your next move again.
