But the money that the casinos through the ages have had, didn't just appear out of no where. That money has been spent and played and lost by gamblers all over and recycled through and all the while, the casinos are winning more than people are winning in the casinos.
But this is only a natural law. Say that if you had a supermarket in the local town, and people needed bread, they would come to you to buy it. You would sell it to them at a slightly inflated price to make money. You wouldn't sell it at cost and then give away another loaf of bread as a gift for coming in and buying one loaf. This would put you out of business. The same goes for an online casino.
Casinos are here for business and their business is the business of hosting gambling games where their objectives are to make as much money as possible. And the same would go for any business or person in business. But the casinos have a special way of making in their casinos. And I am not talking about special dinners and late night comedy shows.
Having figures and odds totaled into how certain games work is called the house edge and this is how a casino makes its money. A casino wouldn't be here if it couldn't make money and you wouldn't be at the casino if you didn't have that chance as well to win a lot of money.
Generally the odds of beating the house are ridiculous, but there is still the odd chance of hitting it big that continues to draw people back to the casino. Also the casino can't just continue to take and take and take without giving a bit back, or else no one would want to go and play without the chance of winning.
So now you can see why all around the world casinos are big business and even in the recent light of new legislation in the US Congress with the passing of a bill restricting gambling online in the US, gambling and online casinos go not seem to be slowing or going anywhere else for a very long time.
