What do the face icons mean? For example the icon that indicates SET. Please let me know what all of them stand for.

Hello Theresa,
Thank you for your question about the legend icons. Gray means the snipe is set. The smiley means you won. The yellow "wink" means you won an item in a group so it shut off that particular snipe.
Please let us know if you have any other questions, or require other assistance. We are happy to help.

thanks

You are very welcome.
