Best Online Casino Bonus Codes

Bonus CodesBonus codes is a common offering by most casinos in the United States as well as in other parts of the world. There are also different kinds of bonuses available to players. These range from welcome bonuses when you first sign up at a casino, to match bonuses and many other types of bonuses that you receive the further you progress in your online gambling journey. Casinos use these bonuses as a marketing tool to attract new faces to the casino, but also to keep existing players. Over and above the regular bonuses, online casino sites also offer exclusive promotions that run for a period of time and include great prizes. To get these promotions, customers usually have to provide bonus codes that can be obtained in various ways. Casino affiliates are known to give out bonus codes. But, game suppliers sometimes hand these out themselves.

Bonus codes usually unlock extra special features to existing promotions or gives you access to a hidden promotion or a special feature to a regular bonus that you would not ordinarily get. Some casino bonus codes give you free spins, while others might give you more free money to use on your favorite casino games.

How they Work

We now know that bonus codes are used to claim casino bonuses or to unlock an added feature of a bonus. Here’s how the process of claiming, and using your casino bonus code works:

  1. Visit the casino that awarded you with the bonus you now want to claim
  2. You should already have the actual bonus code with you at this point. Like we’ve explained previously, you get this directly from the casino on their website
  3. Enter the code in the box assigned. Make sure to enter the correct code
  4. Click on the ‘apply’ button or any other button with a similar function
  5. The bonus should be credited to your account once you’ve completed all the steps above

Casino software developers often give away their own bonus codes. This kind of bonus code typically offers boosters for the casino game developed by that software developer. However, bonus codes offered by game developers are not limited to boosters, it can also be free cash. Microgaming, NetEnt and Reel Time Gaming are examples of software providers that offer casino bonus codes to all its customers.
