There is no way to overcome the house edge, except with bonuses (and that is not guaranteed, and you may not even get paid if the casino arbitrarily decides you may be a "bonus abuser"). There is NO system that works, it is mathematically impossible. I think most people on here play for fun, not for money.
I play for money, so I don't play casinos with much of my own money at risk. My advice to you would be don't play casino games as the house will always win. Cashing-out when you're winning doesn't work unless you never put money in again. If you want to win money, my recommendation would be to study a game of skill where you can play against human players (e.g. games like backgammon, gin rummy, head-to-head BJ or poker). Human players make mistakes and you can earn from this. But you have to study until you are very good, at least 10% better than the average player, in order to overcome the house rake and variance. Only then can you start to play for real money, and only against weak players. Find a game that suits you, study it on the web, buy and read books and practice, practice, practice. You need patience and determination. It's not easy money, if it were easy everybody would be doing it, but that's to your advantage, If you put the effort in you'll win from those who don't, or from those who just play for fun. As English is not your first language it will be even tougher for you.
Good luck my friend!
