First of all learn game rules or examine how slots work by playing in game mode with free money. Search for explanations and descriptions how betting works and what everything means, so that Asian lines wont confuse you. Wait, watch and observe. Play with fake money as long as possible. Dont rush to play with real money and always set limits on how much you can afford to lose.
I second this, one of the main issues with those that try to gamble for the first time is that they do not use the option of gambling for play money in order to familiarize with the website and with how the games they may like actually work, if they did this and they tried the strategies that are often shared to win at gambling and they realized they were false then they could decide to gamble and simply take it as just another hobby, but instead they actually try to make money with it and that is when their problems start.
But I am sure that most people for the first time try gambling not because they want to have fun, because basically they play trial and error, whether they are prior to being caught in other people who win some money from gambling, and therefore they will try their luck is in him to produce several cents.
Not many of them are gambling with toy money or demo fashion, most of which I know that they hold a deposit and then play. If they get a victory at the beginning of playing gambling, it is very likely that he is not aware of gambling, then he will continue to try it again at a later time that will result in addiction.
To reach the point of gambling pleasure I think it requires a far process.
