I feel like gambling pattern 4 is what turns gamblers into addicts. When you gamble and complete one pattern mostly its gonna be called luck (by yourself of course). Give in enough time so you will one day do epic comeback for sure. It may take days or it may take years! But it will happen. And your brain will quickly consider it a epic comeback that shows your skill. Your chemistry will force you to play more and more. And you become typical gambler.
