The casino game or roulette did not start out as a money making venture for the players. In those days, players were only given drinks when they win at the casino games. This was in those days when casino games were played at bars only. But as time went on, things started changing; people started playing and being given monetary reward for their efforts.
The same idea of playing the casino game of roulette was transferred to the internet and people started playing for money online too. Right from the money you are registering for any of the online roulettes, you are expected to deposit some amount of money into your account with which you will take part in the online casino games. You will also be paid accordingly when you win.
Before long, very strong competitions started coming to play in the online casino. Many individuals were buying online casino software and setting up their own online casinos. The desire to gain more patronage by each of them tended to increase and this really took the online casino to another level entirely.
In order to gain more popularity and attract more people to play online roulette with them, the online casino sites started giving out some amount of money for free to players to start playing. Though, you are also expected to add some money to the amount you are given by the online casino companies.
The amount of money you are given is called a bonus. It is also a very special form of bonus that is called non-cashable bonus. This means that you can not withdraw the bonuses from your account. It is true that the bonus will form part of your account, but it is also true that you will never be able to spend that bonus. You really need to put this into strong consideration
The online casinos have a way of preventing you from withdrawing the money you are given as bonus. They can decide to remove the bonus when you have made some winnings and you are about to make withdrawals. They can also decide to leave the bonus in your account without allowing you to withdraw it. The bonus will remain in your account until you lose it to betting.
