The tree in Let It Fall starts with 50 leaves, and one falls for every item you log through the challenge.
It counts quantities, not taps. Log a bag of six old candles as one entry with quantity 6 and six leaves come down. When you leave the screen and come back later, the leaves you've earned since last time drift down while you watch. (If Reduce Motion is on, they simply disappear.)
To make an item count, add it from the challenge screen using the Add Autumn Items button. That gives it the LetItFall2026 tag, which is free for everyone during the event, even without Premium.
When all 50 are gone you get bare branches and a message with your total. You can keep logging after that. The challenge keeps counting; the tree just has nothing left to drop.
I added it because a checklist of eight steps tells you what's done, but not how much. The tree is the "how much".
