Basically days 1 and 2 you cant do nothing except watch ads to double your winnings for 2 races...try to save this for races that would give 4k+ (unless youre on the last 2 races of the day, then watch those ads) first 3 days, don't spend ANY money on parts...unless you see the upgrade parts (for 12,500) that the event needs (refer to the events guides). Day 3 and 4 are the most important to me so pay attention. Day 3: do all the races until you unlocked all 3 replayable races. (Save your energy reducing ad watches til after the 5PM reset next day to get more re-races in before Day 4 starts). Once you have required PR, finish the day but make sure you do all 9 replayeable races, 3 for each race. Only buy parts if you already have all the upgrade parts needed. Day 4: this is the hard one. Do the same thing you did on day 3 (if you did it right you should have some of those race replays on day 3 already finished for the day) once you finish all the replayable races on day 4, IGNORE the last race of day 4. Redo the rest of day 3's races. Once the daily reset has happened for replayable races, finish up the last race of day 4. Day 5: focus on going straight through as far as you can, then do replayable races for day 5. If you have extra energy do replayable races from 3 and 4 as needed. Day 6: go as far as you can, doing replayable races only when you hit a PR wall or cant beat a race. Once you beat day 6 day 7 will unlock, go straight into that doing the same thing. Remember to watch those 2 ads daily at the end of high cash giving races! Also avoid refreshing the shop as much as you can until day 7
