We have also included below some notes on bonus types for newcomers.

Here are some basics about the bonus systems offered by the online gaming sites:

1. Read carefully the section 'Promotions' you will find on every casino website, especially the 'Terms and Conditions'(T&C) of each individual promotion
2. What is called a bonus, is nothing but a credit given to players for wagering.
3. There are always specific wagering requirements which vary from casino to casino and are specific to the game type, the currency and even the country where the player is located.
4. Before a bonus can be withdrawn, the bonus amount must be wagered a number of times as specified in the T&C. It could be on the lower end 10 times the bonus amount. In this case, if the bonus is e.g. $50, you must wager $500 before you can cash in. On the upper end, it could be as high as 60 times the sum of bonus and deposit. If e.g. you claim a 100% matching bonus up to $50, you will have to wager (50+50)x60 = $6000 before you can withdraw.
5. The bonuses belong also to two different categories.
   
   1. Cashable bonus
      You can withdraw this bonus once you have fulfilled the T&Cs
   2. Sticky Bonus
      This bonus is only for wagering and cannot be withdrawn. When you want to withdraw after satisfying the wagering requirements, the bonus will be withdrawn from your account by the casino or, in some cases, will be left in your account for future wagering. Read the T&Cs carefully!
      
6. Welcome Bonus
   Also known as New Player bonus  is given only in connection with the initial sign up. Following are some options of the welcome bonus.
   
   1. No Deposit Sign Up Bonus
      Transferred to your casino account after registration without the need of any initial deposit on the casino account. However. the winnings from this bonus can only be withdrawn after fulfilling the T&Cs. In many cases, there will be an upper limit of what you can withdraw. The rest will be removed from the account after withdrawal. Therefore, don't you play, e.g., a progressive jackpot using such a bonus. Imagine, you win the jackpot, but can withdraw only $100!!
   2. Free Play Bonus
      This type of bonus is becoming increasingly popular. You will read something like:
      Claim $1,000 free casino credit and 1 hour to play! You can keep all your winnings above $1,000.
      It means the casino provides you with $1,000 fun money and 1 hour time to play various, not all, games and, if you are lucky to win, transfer the winnings above $1,000 to your real casino account. But, WATCH OUT! Read the T&Cs very carefully from top to bottom. In most of the cases, you will find that you cannot transfer all your winnings above the credit given to you, but only $100 or $200 after you have deposited a certain amount in your account.
   3. Sign Up Bonus as percentage of deposit
      You may get e.g. 100% matching bonus up to $200. That means for any amount you deposit up to $200, you get an equivalent amount as bonus deposited on your account.
   
   
7. High Roller Bonus
   Whereas the welcome bonus is given only once to a new player, you can claim the High Roller bonus at any time, as long as you are ready to invest a fairly large amount of money in a single deposit, e.g. $2,000, to receive $800.
8. Preferred Deposit Method Bonus
   Each casino has certain preferred payment systems like NETeller, Click2Pay etc. If you choose any of them, you will receive 10% or 15% of your deposit as bonus whenever you use the system. WATCH OUT! Wagering requirements are valid here also.
9. Refer a Friend Bonus
   If you recommend a friend, you will get a certain bonus after your friend has wagered a certain amount.
10. Loyalty Points
    The casinos are interested in keeping you as a loyal player. So they may offer you 1 point for each $ you wager. When you have collected a certain number of points, you may transfer them to cash.
