It's no secret that different slots games have different payout percentages. These payout percentages usually range from about 70 to 98 percent, and depending on the percentage that the game you're playing is using, will obviously be the largest determining factor in how much you will win. The payout percentage of a game will not always be listed on the paytable chart, or anywhere else that's obvious on the outside of a machine. If it's a physical slots game you might have to call up the instructions or carefully read the fine print to find the payout percentage. With online slots the payout percentage is usually listed somewhere in the help section. You should take the time to research and familiarize yourself with the payout percentages of all the different games, whether you're playing in a real or virtual casino. You can always mix up which games you play, but if your major aim is to win as much as possible you obviously want to play the game with the highest payout percentage the majority of the time. .
