Getting to Know Online Casino Bonuses

The most common online casino bonus is welcome bonus. However, this is not the only type of bonus that you’d find in the best online casinos in the UK. The following are some of the popular types of casino bonuses that you can take advantage of:

  • Welcome Bonus

Every online casino offers this kind of bonus. It’s their way of attracting new players and getting them to sign up and play. Some welcome bonuses have no deposit or have very low deposits.

However, in most cases, an initial deposit is required. In return, you will get free cash and in some cases, free spins. A wagering requirement applies to the bonus, which you need to comply with in order to withdraw any winnings. Some casinos also require a bonus code.

  • No Deposit Bonuses

This is a rare offer. However, some online casinos offer no deposit bonuses. It’s exactly what it’s called: players will get free cash or free bonus without depositing any amount. You only have to register and you will instantly get free spins or bonuses which you can use to win real money.

  • Reload Bonuses

The welcome bonus and the no deposit bonus are both available only for new players. Reload bonuses, on the other hand, are available for existing players. In this type of bonus, you will get more additional bonuses and free spins when you make certain deposits. This is usually offered for special promotions or on certain days.

  • Free Spins

Depending on the free spins offered, these may be offered for new players and existing players alike. These are usually tied on certain slot games for real money. The terms of the free spins may either be dictated by the online casino or the game developer.

  • Loyalty Rewards

A great online casino knows how to reward its loyal players. Lucrative loyalty rewards are the best way to keep players rolling. With loyalty programs, players are rewarded points for playing and depositing. You get extra perks, rewards, and special benefits in return.

  • Refer a Friend

Just like how referrals work, you get rewarded when you refer the online casino to a friend. When your friend signs up, you get a bonus and other perks.


While online casino bonuses are attractive, you must always consider the terms and conditions that are usually attached to them. Make sure that the wagering requirements are not too high to the point that it’s already impossible to cash out your winnings. 

Aside from the bonuses, promotions, and rewards, you need to consider other things as well before choosing an online casino. These include licensing, safety and security features, games offered, banking options, and customer service, among others. Once you’ve chosen an online casino, it’s time to register and claim your first bonus. Have fun and gamble responsibly.
