This is pretty simple. We start with 10 random things, such as names of countries around the world, or colors, or actresses, and you have to list one thumbs up and one thumbs down. And everyone starts with 10 points
So let's say you have:
1) Captain Picard 10
2) Captain Kirk 10
3) Captain Janeway, 10
4) Captain Kangaroo 10
5) Captain Ahab 10
6) Captain Pike 10
7) Captain Sisco 10
8) Captain Crunch 10
9) Captain Saru 10
10) Captain Crozier 10
You would vote like so:
Captain Picard +1
Captain Kangaroo -1
And then it becomes:
1) Captain Picard 11
2) Captain Kirk 10
3) Captain Janeway, 10
4) Captain Kangaroo 9
5) Captain Ahab 10
6) Captain Pike 10
7) Captain Sisco 10
8) Captain Crunch 10
9) Captain Saru 10
10) Captain Crozier 10
