Green Dots only on top section
TO actually submit the solution, you only have to place the green dots in the top 3 sections (left to right). The middle 2 sections and the lowest section do not actually need the green dots... so that could save you up to 15 green clicks (obviously to learn and go thru the clues you will click some of these anyhow, if not most of them).
But that could save time as well. Hope that helps some of you.
