Apologies for missing out on this one. The way it works is around winning Episode Races. If during the time of the Soda Circuit you win 3 Episode Races, you will be able to get 50 Gold Bars.
Xarly! It is difficult to do. You don't always have boosters: the players always buy. And in the top levels it takes a little longer to get through the levels. The event doesn't make much sense in my eyes.
Please fix the font size again. Many have problems with it and especially those who already have an eye problem.
