For example, if a slot machine has a house edge of 6%, it would translate to you getting $0.94 for every $1 spent. At this point you might be asking: if that is the case, how come we could profit from this game?

Well, for one thing, slots, whether online or land-based, does not give you $0.94 each time you make a bet of $1. What it does is it gives huge payouts at lucky times.

So if there are five people, and four of those did not win anything at all, the casino already profited by giving the fifth player only a percentage of what the other four players have put in. If the four players have put in a total of, say, $3000, a lucky $1000 jackpot of the fifth player could be seen as huge, wherein actually the profit of the casino is larger.

Two points should be made here. One is that the winnings of slots, whether online or land-based, do not rely on the players preceding you. So even if you are the first one to play, you have equal chances of winning as the hundredth player.

The second is that this fact should not discourage you from playing. Do remember that online slots is a gambling game, and that means investing enough money in a risky place in order to have a chance -- and only a chance -- to profit.

It is just like any other investment. Stocks, for example, also have chance as deciding factor on whether or not the investment would profit. The good thing about online slots is that the chance factor and payout percentage is fixed.

That means you only need an awful lot of luck in order to score a game with a high enough payout percentage. Some rare games have payout percentages of 99%, which means you could profit more than you could lose.

Some online casinos brandish the payout percentages of their games. While some of these may be true, most use this as a selling point, a marketing strategy to entice customers. The best move is not to rely on what online casinos say, just strategize well by managing your bankroll and winnings. By doing so, you'll surely avoid getting bankrupt, and profit most of the time.
