Wow...I totally did not understand the "sets" at all as I was thinking "icon" meant the target shape and location (again thinking, for example, the top 3 bumpers were one complete set, not just 3 of the 8 bumpers in the set). Thank you so much for clarifying that. Now I will go back and replay this game with the newly understood rules and see how I do.
I hope you end up publishing a season 3 sometime soon.
