What do I do when my board is full?

Look for pairs you can merge — merging two items frees a cell. Deliver anything an order card is asking for (glowing cards are fully deliverable). Sell items you don't need: tap the item, then tap the sell chip at the bottom — you can always undo. From Chapter 7, you can also move spare items into the Supply Closet, but remember: items in the closet can't fill orders.
