This is a simple but very effective strategy. Like Standard Deviation, in order to make the One Play Strategy work, you must also choose slots games that offer Equal-ratio payouts. This method works best with games that offer the biggest jackpots, and you play only the maximum bet. These are the steps. You start if any one play wins a payout at 1x-3x (1 to 3 times the amount bet) then you make 1 more play. If any one play wins 4x or more, then you make 3 more plays. Otherwise you stop playing immediately. Take note of those slots where such strategies might seem to work, and those games where they do not work. Note: there are a lot of people who don't believe in One Play slot machine strategies. They usually say that it is impossible to win by just using one kind of bet. The best thing to do is try the method out for yourself, if it works for you than it does not mater what anyone else thinks about the strategy. Also here are some things to consider when deciding whether to use the One Play Strategy. There will always be times when a slot game does not pay for awhile, and then "pays off" in the end. However there also are times when a slot machine game will just keep on paying. Even a jackpot does not last very long if you go around feeding slot machines that do not feed you back. If you can keep, on average, 1x from every 3x win, you will do better than to win the largest jackpot.
