Almost half of the games you mentioned in your blog is luck based game, so there's no skills or techniques needed obviously.
Indeed true, but i think, there's really no gambling game which onlu requires skills and technique. Wehther we like it or not, luck would always be a part of the game. The only gambling game I know wherein skills would be necessary is, sportsbetting. Observation and alaysis would be a good thing to do in sportsbetting because a gambler could base on the win-loss record of the team or player he would engage himself with. But if you would be unlucky, things could still fall apart.
Except card games I am not sure any other gambling games require any skills. Almost all of them are luck based games. Initially you can use your skills to control the game but eventually the house takes over and only luck plays. I have tried many techniques and skills but most of them won't work after some time.
Card games I think will also require luck. Good cards would give you the win and if you are not that lucky enough, you would lose the game, as simple as that. This only shows how huge luck is, as a factor in gambling. There would be days wherein the game would be in favor to the player, and days that it won't. So just enjoy your experience.
