Online casinos are competing with each other in offering better and better promotions to players in order to lure a visitor to become a player, and secondly to keep a player.
Thus, they have created promotions that have the aim to attract players and keep them in a casino for the long run. Generally, a casino would offer promotions like sign-up bonuses, deposit bonuses, referral programs, player or comp points that are convertible into real money, and other promotions.
The sign-up bonus is offered at signing up at an online gaming website.
If the sign-up bonus is not determined by the first deposit, than it is usually a few ten dollars, however some casinos may go as far as to pay 900 dollars only for signing up.
 However, if the sign-up bonus is in percentage, it is most probably connected to the first deposit. In this case, this is the same with the first deposit bonus. This means that the player will receive a certain percentage of his/her first deposit, usually 100 percent, i.e. the casino would double the deposit.
Deposit bonuses, which we have mentioned before in connection with the sign-up bonus,  are another type of promotions included in the awards system of a gambling website. The amount of the deposit bonus depends on the amount you deposit.
 There is the first deposit bonus that depends on the amount you deposit for the very first time. There are also second deposit bonuses, and so one, offered for the second, third, etc deposits. Other casinos would offer deposits bonuses on deposits made on a certain day, or for all deposits of a certain amount.
The loyalty points are also a common form of casino promotion. These points are also called player points or comp points, and are given to players simply because they are playing at the casino. However, not all of the games that are available on in a casino bring the player loyalty points. These points will be gathered in the player’s account and converted into real money at the time of the casino payouts. Poker rooms that are a part of the Poker Rewards System, offer the player points that will be gathered in the Poker Rewards account.
Another type of promotion offered by some casinos, is connected to the deposit method and it is connected to some preferred payment methods. Some casinos offer a bonus percentage for a deposit made through Neteller, Click2Pay or Firepay.
Other promotions offered by casinos, include chances to win a trip, chances to win a free place in a tournament, or other sweepstakes.
Generally each casino would offer something in plus in order to keep its players playing with them. The player can choose the casino that offers the greatest promotions possible as this is also a way of gathering more money by playing gambling games at an online casino.
