According to the article you posted;

Almost half of the games you mentioned in your blog is luck based game, so there's no skills or techniques needed obviously.
That's right based on the games that you have mentioned so far it is most likely on luck and not a skillful based so I don't trust you. One of the games that requires skills and techniques that you have been mentioned is the video poker or the poker because in poker it requires a high skill and also a techniques in order for you to win on the said game. Just like the old times there are so many people that are required skill based game gamble in order for them to earn and to exercise their mindset.
Probably, he thinks that these games really require strategies and techniques but in reality, it doesn't. Poker needs courage and patience for you to win in this game but still if your card aren't good enough for you to win then in some point, it is still a luck based game. Maybe this thread will make him understand the difference between luck-based game and strategy-based games in gambling. Mostly, I prefer gambling in luck-based game to test my fate and to know if I'm lucky enough to win more money. All of the players in luck-based game have lower probability of winning so it is fair. But it is true that skill-based game in gambling is more essential and it can really exercise your mind to relieve stress.
