The "Stack" is the 9 cards on the left and the "Feature" (the Chandelier in this case) is the 9 cards on the right. Because of the 'Tough Love' card, I scored zero (instead of 30+ (about half my total)) points on the Feature, so overall, I failed miserably. You need 60 Points just to make a showing. Note to Self: Cheat next time and leave the top-center-left card out of the game. 😋
P.S. The 2 top-center gray cards and the 9 on the right are only used in the Solo Mode.
