· Speed counts! Click through the tiles as fast as you can – there’s no penalty for a wrong match except the time lost by clicking.
· The devil’s in the details! Some images can look quite similar – so it pays to pay close attention to the images. For instance, when you see a planet, it may be the Earth, Venus, or Mars. It pays to notice the small differences.
· Don’t waste too much time searching the lower layers until the upper layers are completed. The time it takes to look for images that may be covered in hopes of a large bonus can cost you when the clock runs out.
· Above all, have fun! Otherwise, what’s the point, right?
