# Conveyor

Inverse operations · 30 levels

Load the belt so every ball comes out right.

## How to play

- Tap a tile in the tray, then tap a station on the belt to load it. Tap a loaded station to take the tile back.
- Balls ride left to right through every station in order. Filling the belt runs it automatically. Replay belt watches it again.
- Every ball must come out as its number on the right. A ball pops if a ÷ isn't exact or it drops below 0.

Work backwards from an output: undo the last step (× becomes ÷, + becomes −) to see what must arrive there.
