Yes. Once you’ve added at least one clue, an ‘Reorder/Delete’ button will appear below the list of clues on the Create or Edit Hunt screen. Tap this, and the clues will each show a three horizontal line ‘handle’ to the right. Drag a clue up or down to move it relative to its peers. You can also tap the delete button to the left of a clue to remove it.
When you’re finished, tap Done.
