This type of offer is just superb and one that all the big-name casino sites like MrGreen, UniBet and Casumo will have on offer for you. This bonus is usually offered upon sign-up, although sites will also send them out to regular players who use their slots often. As a rule, they are normally given out to players in batches of 10 or 20 Free Spins to use on a certain game. The reason behind this is that the casino sites will identify games they want to promote to players and use the Free Spins as a way of encouraging or generating consumer interest. Once players have used their Free Spins up and have become immersed in a particular game, they will then be more likely to carry on playing afterwards.
Obviously, this type of bonus is very lucrative for the player, as you are getting more spins and chances to win without using any of your own money. If you are a loyal customer to a certain casino site then you may find a lot of Free Spins coming your way! The increased playing time is a very effective way of building up your bankroll with no risk to your finances.
Free Spins may also be given out after setting up an account on the condition that you deposit a certain amount of money. These will work in the same way as the Free Spins you are awarded naturally, in that you may have to use them on a certain game and will likely receive a batch of a set amount to use.
The amount of Free Spin opportunities and the games they are to be used on will vary depending on the individual campaigns the casino site is running, so keep your eyes open for the best deals as they come along. As with all bonuses, keep an eye on the terms and conditions attached to them so you are fully aware of any rollover or wagering requirements.
