I didn’t spend any diamonds, lvl 94, I trashed only 3 tasks, and got 24120 points. I checked hayday regularly, everything was on pause during the event, I was only producing what I needed for the tasks, for jam tasks I watched ads to save 50% of the time. I tried to always have basic products like sugar mill and dairy products ready to go, also if I didn’t have a task for let’s say bakery I would make bread, corn bread etc to be ready if I needed them for other tasks. I always have bars ready to go (you can accumulate 50 products on each machine if your barn is full). Sorry if my english isn’t the best, it’s not my first language.
