When you make a casino withdrawal, you are getting back funds that you have put into an account with an online casino. Preferably, you would like to arrive at this point after making a profit, although this is not always the case. While deposits often happen seamlessly, and often rather automatically, such is not the case with withdrawals. There is more of a "human" process involved, and if you are new to the world of online gaming, you should know that it does not happen nearly as fast.
At some casinos, customers have experienced more problems than at others, and in fact, the idea of "lightning-fast withdrawals" have been used as a selling point by certain casino operations, and at many places, the process is not painful at all.
The objective when you make a deposit into a real money casino account is to eventually make a withdrawal from that account. After all, you would like to cash out, especially if you have experienced winning sessions. The way the business works is that you, as a player, have made the deposit, or purchase, with an online casino operation, and you continue to play and keep a running total of your balance, which will reflect wins and losses, not to mention bonuses you may gained along the way.
In this way, it does not work like a land-based casino, which is generally "cash and carry." So the process of "settling up" does not happen as often. It is not uncommon for people to play for a long time before making any move to cash in their balance.
But when they choose to, how do they go about doing it?
Well, in some cases the same method that has been used in making the deposit into an online casino is used to take the money out. For example, at All Jackpots Casino, Canadian players can use Click2Pay, ClickAndBuy, InstaDebit, Skrill (re-branded from Moneybookers), Ukash and Visa to make both deposits AND withdrawals. They also allow the same with MasterCard, although it should be noted that usually, it is Visa and not MasterCard that can be used for withdrawals.
Generally speaking, it is less problematic for a casino to send the funds to you with the same method you utilized to send to them. Of course, in some cases, this is not possible. With MasterCard, for the most part, and eCheck, the way the funds usually get sent to you are by check, which can take a few weeks to get to you, or by bank transfer, which of course takes less time.
It is certainly advisable to check with the individual casinos you're playing at in order to ascertain their withdrawal policy, because they all have one. There are customarily maximum and minimum amounts that can be withdrawn at any one time, or during a given time period. There is sometimes a fee involved with receiving a withdrawal, which is charged to you not necessarily by the casino, but by the gatekeeper of whatever avenue you are using (e.g., a bank).
Once all of that is understood, what you simply do is go to the cashier in the casino software itself or somewhere on the website (in the case of instant play-only casinos) and follow the buttons to make a withdrawal. You will be asked for some verification information, and the process is underway.
