Ticker

I am looking at the ticker as it runs by, and I see games the following for NHL:

Regular.
Regular surrounded by a white box.
Regular surrounded by a red box.

Is this like normal game, heritage game, game of the week or something?

Please fill me in, I feel lost.

 

There three different hockey leagues.....i couldnt name them all for you but im pretty sure im correct on that one.

 

Ohh, I think I remember reading about the LG Sim league, the LG Fantasy league, and then the CCHL or something?

 

Thanks Tris, a lot to remember, I'll get it stuck in my head though.
