When it comes to casinos, a wager is not just a bet. It's the amount you need to wager to fulfil the promo terms. Every bonus from a gambling site necessarily has a wagering requirement: – You have to wager a certain amount; – Over a certain period; – On certain games; – Before you can withdraw the bonus or winnings received from it. In casinos, wagering is usually done on slot machines. Then, in a bookmaker's office — on betting. It is sporadic that wagering involves tables and never live games.
