How do you line up path in the Mine grassy area?

Do you mean the puzzle to clear a path through the field outside the mine entrance? Unfortunately the path can vary in each game, you will need to use trial and error to work out required path for you. You need to find a way to the hidden cache. Remember where the obstacles are that you find in the field and avoid them in future turns.
