Generally, a free bonus is the most generous thing a casino may grant to the players. With that in mind, the service wants the players to try as many such bonuses as possible. Most of the no deposit bonuses are typically granted after the registration process, for one time use only, but some of them are also available to existing accounts. Plenty of the no deposit casino can be also matched with single or multiple bonuses coming from the same casino. The full list of no deposit bonuses has been prepared and it is still growing. Not all casinos possess the same regulations, as you may have already noticed.
Each and every one of these sites has a individual process of claiming such bonuses. Many of them require using a promo code. In most cases you can freely enter the code into the cashier, however some may be needed to be verified by the support. There are some bonuses that do not have the codes on the coupons, which means that the promo has been automatically added to the given account. This often varies as the casino software may be quite different from one another. Many may require to make contact with the support, others are granted after a single push of a button. Most of the bonuses can be used only on slots, yet there are still some of them that are valid with specialty games and even table games as well. For further information, contact the customer service.
