My Own Tips

I'm only around LV70, but here are some tips I think are helpful for playing without spending money. Check what the clear condition is (what to collect). If you drop too many unnecessary items, you might run out of time. Conversely, if the condition is to collect everything, you need to be careful to collect them without missing any from the start, otherwise, you'll end up searching for the remaining ones at the end. Pay attention to the remaining time. Watching CMs only adds 10 seconds, so if you're significantly short on time, you'll end up having to watch CMs endlessly to clear. When time is running short, prioritize the items for the clear condition and don't force yourself to drop unnecessary items. Use limited items for hard modes, etc. Pay attention to the size of the items and the holes. If the hole isn't large enough, items can get stuck, making it difficult to drop other items, and greatly reducing efficiency. It's particularly troublesome when only a part of an item gets stuck in the hole, making it hard to dislodge. Drop tall stacks all at once without letting them tumble. It's difficult if the holes don't have enough clearance. If you stop the movement once, it's easier to drop them all at once.
