Just speaking from my own personal experience (or stupidity) but i seem to do better on the slots late at night, after midnight, usually between the hours of 12:30 and 2:30 i seem to hit bonuses a lot more often (I’m playing mostly blueprint games btw)
I’m not sure if there is something in the programming or code that says something resets at midnight, giving an extra little chance of hitting something, or less players means more chances – but I’ve definitely been more “lucky” early on
