Have you ever gotten a max win in slots?
If so, what strategy are you using, do you bet small or big?
And tell me what kind of game and its provider.
To be honest, I haven't got any max win in slots and I don't really think there is any strategy to it.
Slots rely mostly on luck and so deriving strategies for luck based games is waste of time and effort.
It could merely be a coincidence if you win it few times using the same technique but it would most probably not work in the long term.
