This is not about cheating but this is what the actual skill which is doing the real magic in gambling. Unfortunately most online gambling for not giving room for you to become an observant of their gambling behaviors/secrets and in more particularly how their seeds are being generated.

This is the reason if you gamble against you friend, you will be having fairly 50% of chances to win whereas online gambling houses are claiming to have "the house edge" which is the real destroyer of everything.

Being observant and remembering past experience to avoid one particular incident a kind of things we can apply in gambling but the modern gambling environments are highly ultra faster one which will not allow you to think over anything so that they can keep you always in excited level so that you can gamble and lose and then move away.
