You need luck with those games, I for once, played Gold Star a few months ago and random feature 
appeared more than I expected. I played for an hour and my balance was quadrupled.
I kept pressing refresh after a big win and big win kept coming 

In my experience, when the game gives you nothing within 40 spins, get out!
But then again, that might just my conscience speaking 
The graphics are outstanding though, run very smoothly.



A parenthesis here mate; about those first 40 spins;
have you ever felt sometimes those first spins are terrible and then you reload the game and it seems your luck have already changed for good?
