When approaching from any distance you can change your "shot choice", lower left of the window, to pitch or chip. Punch does not work, and Flop is only when you are within 35 yards or so.
You will then get the contour of the green as you see it from your perspective. If the squares (2 feet each) are red before the pin and blue after the pin you have an uphill approach.
If the grid is blue before the pin and red after the pin you will be hitting a green sloping AWAY from you.
If you right click your mouse, you can choose ZOOM IN and see the dots moving left, or right as well.
DON'T FORGET TO RESET THE SHOT CHOICE TO FULL before you hit.
Good luck
