If you’re already familiar with the bells and whistles of casino bonuses, be sure to check out our list of the best casino bonuses. You can list a single type of bonus, or bonuses depending on their wagering requirements, maximum cashout amount, countries accepted, etc.

How Do Casino Bonuses Work?

A bonus is a form of reward that you get by opening an account at a casino, depositing money, or betting real money. The most common form of a bonus is a credit that you can play with and which, after fulfilling certain conditions, will be credited to your account.

Other common forms of bonuses are what are called free spins, or the refund of part of the money lost (cashback). Bonuses extend your game and give you a second chance if you lose.

You play further, even if you have already lost your initial deposit, and although the bonus conditions are often very restrictive, you still have the option of converting your bonus into withdrawable winnings.

Types of Online Casino Bonuses

  • Deposit Bonus – You get bonus credit based on the amount you deposited. Most often you get 50% or 100% of your deposit, and sometimes even 200% or 300% or more. The maximum amount of the bonus is generally limited. Deposit bonuses are promoted by offering offers such as “150% bonus up to € 150”. However, pay attention to other bonus conditions, especially wagering requirements and maximum withdrawal limits, both of which are very important.
  • No deposit bonus – It is popular especially among the so-called freebies, players who want to earn money without taking any risk. It is most often given for registration, without the need to deposit money. Usually, it amounts to around € 5 to € 20, and complying with the conditions for this type of bonus is usually quite difficult.

  • Free Spins – You do not get free money, but you get free spins on popular slot machines selected with pre-paid credit. The winnings are not immediately credited to your account. They form a bonus credit, which requires you to fulfill additional conditions (such as a no deposit bonus). Only after fulfilling these conditions, the casino will credit your account with real money, which you can then withdraw.
  • Cashback – The casino gives you back some of the money you lost.
  • Loyalty Program – Every casino tries to keep the best players, and sweetens them with something special. The benefits offered in loyalty programs are difficult to catalog.

Other popular benefits include lower wagering requirements for bonuses, higher play limits, and even higher withdrawal limits.
