If you close it at 20 people, you can just give every person 5 random spots and the final winner 8 picks, 4 first and then the other 4 in succession with the others, with the other 3 winners each getting 4 picks in the original succession
[quote name='briansraregames']I think that we have enough people in the pool to operate it successfully. If we can't get the last pool full, what we'd probably do is to have "push" spots on the grid. If the score falls on those spots, it would be a draw.[/QUOTE]
