Deposit bonuses are offers that can be used when you deposit a certain amount: be it 10 euros or 100 euros. For this, you will receive a few things from the casino, such as a percentage of your deposit as a bonus or a bunch of free spins or casino credit. For example, if the chosen portal offers a 100% bonus, it means that when you make a deposit of 100 euros, you will be given an additional 100 euros as a bonus right away. This bonus can certainly also include free spins and free bets in various games, which are usually given in advance. New casinos relatively always offer them, but also observe what requirements accompany them.
