97%, 98%, 99% Payout ratio on your favorite slot machine, wow, does this mean you can be guaranteed wins returning that much? The truth is, no, not likely. So what do these numbers mean? Well, here is a little fact for those who aren't familiar with how payout percentages are calculated. The way things are done is as follows; the percentage is calculated over an extended period of time and through tracked history of payouts and what is being paid out when. Once the numbers are in, they are studied and an average percentage ratio is calculated for each machine stating that each particular machine will eventually give out a certain amount back within the year. The average payout percentage ratios seen in slot machines is anywhere from 75%-99% but unless you can sit and play non stop 24 hours a day, it is highly unlikely that you would receive 99% or even less than that paid back to you. Remember the House always wins in the end. However, if you would like to play with better odds in your favor, sticking to online slots is a wise decision. Since online casinos have much fewer expenses they can afford to have higher payout ratios and therefore give you a better chance at winning. This is always a very good thing to keep in mind when choosing a game because you want to be sure you play were you can get the most for your dollar.
