All I can do is use trial and error, and maybe have 5-6 different browsers up with 6 different ways to solve/beat this puzzle. I know I have it in me. But I need to get ready to eat lunch. I can worry about this later, thanks for the hint.
Use one of the red icies in the middle to then place a second one (at the bottom) and then use the bottom one to place a third one (at the top). The rest should be a bit easier if this is understandable.
