I didn't know this bug but if you are a regular bettor regardless of the amount, You will surely get a reward on hourly contest since there's still only few users participating on hourly contest and you can see same user that win every hour. I'm surprised when I visit today some new user that actively playing on the casino and chatting on live chat box.
Do you know what happened to RW? He is not active anymore for consecutive days or I'm just sleeping whenever he is active?
Even at hourly, if you are a person who gambles very little like me, then you are not going to be winning much. I did managed to win a few times at the bottom and by luck but that was really just a situation where nobody gambled at that time zone, on times when it is more crowded that becomes something impossible for me.
The only reason is that I rarely gamble with any meaningful amount, I gamble with as minimum as it gets and I do not put all of my gambling in just one hour neither, I spread it to the whole day, which makes it hard. If I end up grinding hard with all my money then of course I can win, I will even be first at times, but I do not see the point of it, I gamble the way I have fun and that is much better.
