Bonus types in Online Casinos

Welcome Bonus

The welcome bonus is quite likely to be one of the most common bonuses you will see at a casino. The customers are rewarded with some cash as soon as they sign up. The matching deposit amount might vary for different casinos, and customers need to check and compare different casinos before selecting the final one.

No Deposit Bonus

No deposit bonuses in the form of some cash are given to customers to try out the new casino and have fun without actually risking an ounce. Most of these no-deposit bonuses come with their own set of terms and conditions, so rookies are advised to go through the same before signing up with the casino.

Reload/Deposit bonus

Reload or Deposit bonuses are given by casinos to customers on a fairly frequent basis to encourage them or to re-invite them to their sites and make deposits. For new customers, a minimum bonus is guaranteed on signing up and depositing a minimum value to your account. For example, a customer can be awarded 100 bonuses for a deposit of 10.

Loyalty bonus

Loyalty always pays off is a phrase that is apt for most situations. Just like how an offline casino would treat you if you were a loyal customer, online casinos too keep treating their regular customers with timely benefits and offers. Loss refunds, milestone awards in the form of cash, and additional free bets are some of the different ways that casinos resort to delight their loyal customers.

More Types of Bonuses in Online Casinos

High Roller Bonus

Players who deposit large amounts during account setup or who are regulars putting really high stakes get incentives from casinos in the form of bonuses. These bonuses vary from site to site and are generally a percentage of the deposited amount.

Device Bonuses

Most casinos have adapted to the advent of technology and gradually increased their reach to mobile apps and tablets too. To encourage customers to download the apps and play via them, certain bonuses are categorically applied only when one signs up through a mobile device running either on Android or iOS.

Referral Bonus

Customer acquisition is one of the key focus areas for any business, and the online gaming industry with the likes of casinos is no exception. Most casinos have lucrative referral programmes running on their sites to invite new customers. For every successful referral, bonuses are added to the customer’s account.

Time Limits

Whenever a customer is awarded casino bonuses, it is really important for them to keep a check on the expiry date of their bonuses and the number of free spins that they were rewarded. Certain deposit bonuses require minimum deposits to be made within a stipulated timeframe. Therefore, one must be extremely watchful with regard to the time restriction of the casino’s bonuses to ensure that one does not miss out on an exciting bonus.
