[Kipper is King]

Big green circles appear where you have created plays, so you can activate them. In BAP, a red semi-circle appears by your bench when you are needing to change lines. Sometimes red and yellow circles appear around the puck depending on if it is loose or not.

I've never seen a bunch of yellow circles on the ice though. Can you take a picture of it, or describe how they are positioned?

I'm not sure about the numbers in online versus though, either. I've always wondered what they are too,
