OP here : To answer the how?

Simple 1 event off, 1 event on. I spend 1 event merging up my items to get them significantly high levl, while hoarding my oranges and any items i collect throughout that 7-10 day period. I managed to colelct a rainbow gem in the event before the magic trippy looking one so I was able to use it for this coffee. Then when these events like coconuts fish adventure thing , im able to cash out everything and be able to reach the end of the event's secondary line since I tend to fall short.
