Hi, you are asking for something that doesn't exist for 99.9% of gamblers, the only way you make it fool proof is buy cheating. I play fruit machines and am rather good at them as I have years and years of experience and know what they are going to do a lot of the time and how much I will win and how quick I will win it. I have been known to pouch (wait for others to go skint on the machine) then I play and win. That is giving me an edge but it is not fool proof, my point even after all these years and things learned I still lose now and again so it is not fool proof. Do yourself a favor as you don't know whats going on, don't dream of winning big. Spend your funds on a family member/yourself or a cute girl, leave the gambling to others. Regards
