I lived in this misconception, once before the New Year I had a good profit, and it happened again 2 years in a row.
I thought I was more lucky when the New Year.
Of course this is not true, the casino never changes under the influence of the social factor.
The casino is the same as always no change.
Or maybe there is?
As far as I know, casinos will stay the same as it always, unless there will be some changes in the strategy of a particular casino. No matter what social factor it is or event casinos will be the same. If you felt lucky every New Year then why not maximize it and use it to gain profit that would be great. However, probably it is just a coincidence where you have trigger your luck every New Year because as far as I know luck is randomly triggered it could be triggered on your normal days but not always on special events.
