Anniversary Party quest!

I think the easiest way to do this game when there is a quest. It's actually do the quest part first. It all the tests out of the way, then you got the karaoke machine. (Took me about two and a half days) once that was out of the way did a lot of llama zooms and events. You can put a timer on your phone, which helps you a lot to know when the event starts and when you can use bathroom. Use one cupcake per event for 90 points (only one per event) and I got my basketball court two days ago. I was able to do events with only three Sims. So if you were to just tackle this event doing only events you'll never get the basketball court you have to do the quest first. And there's no way to go around the fact that you need to do llamas zooms. I agree with previous poster you need to stack tasks. I'm not even going to bother to do any more events because the loot boxes were really disappointing and I kept on getting duplicates. I rather send my Sims to work.
