If I remember correctly it was in the first phase when there were 5 golds to the first for each day. I remember because one of the days I spent 2 golds to repeat the game quickly to take revenge and stay first, and it more than compensated me for doing it. In the final phase the daily rewards were even better, but I couldn't be in the top three any day.
I found a screenshot in the forum that I think is from the previous one
