Wave_Rida: The following link has 14 screenshots/walkthroughs. Some just show the setup while others show a step-by-step procedure. There are several people here who are faster than myself most days. Every now and then, I do post the fastest times. My solving skills on the harder puzzles is not as good and my intermediate times are usually a minute or two longer than the big boys. Hope the screenshots help.
