Tidal Tug
Arrange the Sun and Moon around Earth to forecast the height of the tide.
How to play
Drag the Moon and Sun to set their alignment, then lock your forecast. Spring tides happen when they pull together, neap tides at 90° apart — the Sun's tide is about 46% of the Moon's. Five accurate forecasts win.
