Online Casino Bonus Offers Explained:

Welcome Bonus or Sign up Bonus

This type of bonus is offered by the casinos to get new player sign ups at their casino.  They give you that added reward so that you can earn more money.  It’s a great way for online casinos to acquire new players to their casino.

Match Bonus

They are based on a % of your deposit at the casino.  For example, a Gala Casino Bonus offers a 100% match bonus up to £400. Therefore, the casino will give you a bonus amount matching your first deposit up to a maximum of £400.  There are often roll over restrictions meaning to withdraw or cashout, you’ll have requirements that you will need to meet in order to do so.  Check terms and conditions for all match bonus offers.

Reload or Deposit Bonus

Once you’ve signed up and made a deposit, casinos want to make the slot player happy and keep them loyal so they will offer a reload, or deposit bonus, for making another deposit.  Sometimes these are offered on a monthly basis or offered if you use a certain payment method for example.

No Deposit Bonus and Free Spins

These types of bonuses are given to players so they can start playing slot games to win real money, yet not even have to reach into their own pocket!   These bonuses are great because not only can you win real money and cash prizes without depositing anything up front, but you get to see how you like the casino.
