This is how the ''Ultimate Britney Spears Music Video Challenge'' works. The 35 videos are put into five groups of seven. You vote for your favorite video in each group. The five videos in each group with the most votes advance to the Semifinal round. The two videos with the least votes per group are eliminated. In the Semifinal round, the top 3 videos with the most votes in each group advance to the finals. At this point the groups are abandoned, and you just vote for one video.
