A no deposit bonus (NDB) is a type of casino promotion that does not require players to make a deposit to receive it. It is usually a cash bonus, free bet, or a set number of free spins on online slot machines. The value of the bonus varies from casino to casino and is often dependent on factors such as the size of the deposit, the wagering requirements, the type of game, and other terms that may apply. It is a great way for players in Belarus to get a feel of an online casino before they start investing their own money.
