The wagering requirements for a casino are the rules that players must go by when using the bonus. The bonus might need to be used for wagering before it can be withdrawn. Everything the player wins can be withdrawn, and they can use it at any time. Other casinos force the player to use the bonus in a certain number of days, and there are more bonuses that have cash wagers attached. It is possible that an online might write in their terms and conditions that the bonus must be used with a certain amount of the customer's own money. The players who have to bet their own money with the bonus must check how much of their money must be used. Keeping the ration under 40-1 would be helpful for most players.
