When it comes to multiplier the key here is to do different experiments. I am always taking my multiplier on different levels with different combinations. For example, I would start with minimum bet and multiplier set to 150x or 500x. This is just random number, nothing special about it. I just try these multiplier because I want to set the system on loosing end continuously. After this I would suddenly go and change the odds to 10-15x by the time I have lost money so it’s time House has to give me back. Then I would be constant on these multiplier for sometime to gain money. Though it’s not a guarantee but it works for me most of the time.
I am not motivating anyone to use this strategy neither it may work same for everyone.
I’m using this since many months, working just excellent for me. 
It's nice that it works for
you. What else do you need?

It's all for fun, after all. I also have my own strategies for dice game and although I know perfectly well that even a dozen unicorns can't make them work like for real, I keep using them from time to time and they "work" once in while making me happy.
