A big win for me while playing casino is like 100x, it all depends on the x win there. If u compare other providers on one u can win 10x and then all sorts of jackpot sounds is coming and you only win 10x, while other have a big win when it reaches around 100x and that is a big win.
Then there is a difference on a big win and a lifechanging win.
A big win can be life changing but also a 100x also.
And a big win is enough for me to do a redeposit again since i like the entertainment from slots and have been gambling for 8 years.
