Quest for the ways to regularly win at online casinos will probably never end. As long as there are casino games, people will try to find the opportunities to be the ultimate winner. But the chances of finding the solution are pretty small.
In contrast to poker rooms where players compete with each other and initially have equal chances of winning, casino gamers have to play against the house. This is the only option at an online casino. In this kind of battle over winnings the chances are not the same. Online casinos need to earn money, and players are the source of their profit.
But at the same time, casinos do not make special efforts to get players' money. Most of casino games have rules that always give players a bit less chances to win than to lose. The same principle is followed when deciding on casino game payout coefficients. Payouts corresponding to the risk level players are taking should be higher. But casinos always lower coefficients to make the profit. As a result, players find themselves in an unfavorable situation they can't change.
If you are serious about increasing your winning rates, you are recommended to play black jack and execute the basic strategy. For every possible black jack scenario there is already the most optimal decision available.
When you follow the strategy, you start to win more often. Losses will still be more frequent than winnings, but casino edge will be decreased to 0.5%. This is a good result, especially if you compare it to the initial 8-9% house edge.
There is an easier option to win more. Simply find an online casino with high slot payout ratio (98-99% would be perfect), and play only slots machine when placing real money bets. But casinos still take their 1-2% share of your bets. You can't avoid paying this price.
Dispersion shouldn't be ignored if you plan to fight for your casino money. You can achieve maximum possible return to player by placing quite large number of bets (starting from 1,000). If you are not active gamer and play at online casinos from time to time, then actual house edge might be much higher than standard. But it's also possible you get lucky at some point and stay with profit.
