There are no unique skills in slot games, slots are purely about luck. I think you misinterpreted what i typed, i told the OP that if he plays slots with the main intention of profit, then it's better to get out of slots, there are many bets that can use the main reason for profit, just like sports betting which requires strategy & a little analysis .
Well sport betting isn't exempted from from being a game of luck. All gambling games are based on luck, because if truly strategy and analysis is what guarantees wining, then gambling could also be seen as an occupation without anyone kicking against it. The reason they use the word Favourite to win a match or competition is because, there is still a possibility that the opponent could end up becoming the winner, but based on stats the favourite team might be on good form or during their last meeting they beat the opponent. Sports betting is my best gambling game, because it makes you think and make analysis, which might seem as though we are in charge or bear all the credits if paraventure we won the bet.
that is one of the things some people does not understand in gambling because every gambling website you know today does not have assurance and you participating in them and win is based on Opportunity that come for that moment so I know very well that gambling is all about opportunity but many people who owns a website to will tell you that when you gamble in their website definitely you will win thinking that is a website that guarantee a winning in any gambling website so I do pay my people who can move with me that website cannot make you to win a gambling it depends on your prediction because if you predict the same then website a and in website b you will win the same thing if the winning is for you and if losing is for you you will lose in both side
