Ok, so after doing a power session today, taking a break by going to see the Avengers, I came back and knocked this challenge out.
Riley Carr managed to cap a full 14 skills. He had 3 other skills, but none of them made it to level 6-9, and he was the only one in his household the entire time so his score is:
14 skills * 1000= 14000
His Multiplier is 1 so the score is 14000
I had a good time with this one and I will enjoy my first time in the top spot, though I doubt I will remain there for long lol. I'm happy with my score, overall. Good luck everyone!
