Yep, It is the NFAA (National Field Archery Association ) Indoor round. You can shoot a "One" Spot or "5" Spot target. On the " 5 " spot target the Bullseye is worth 5 points with each scoring ring after worth 4, 3, 2, 1 points. The Bullseye has a center " X " ring which you keep count of. So if two or more people shoot a " 300 " the winner is decided by the " X " count. Of course like with all NFAA shoots, you compete in different classes depending on your equipment.
You shoot 12 rounds of 5 arrows from 20 yards, with a max score of 25 points per round. You are going to meet a lot of good folks shooting target archery, and see a lot of different equipment. I did the whole target archery thing for years ,both dots and 3D. I had a lot of fun and shot and lost & broke a bunch of arrows.
