First deposit bonuses, also known as welcome bonuses tend to be offered by the majority of established casino brands and equally the most popular. As the name suggests they’re dependent on a first deposit to be made, as opposed to a no deposit bonus (no deposit needed!). The minimum deposit to be eligible for the bonus can vary from casino to casino but will be referenced in the terms and conditions.
First deposit bonuses can also often include free spins on top of the cash bonus. The number of free spins can again vary but are often limited to select slot games.
Match welcome bonuses are pretty simple to understand, the casino will match your deposit up to a maximum limit which they will define. For example, A £50 deposit on a 100% match bonus will award you an additional £50 from the casino, making your account balance worth £100 in total.
