35 dancers have made it to the next round, day four of auditions on Season 18 of So You Think You Can Dance where they will face the toughest challenges yet, similar to what they would at real auditions while seeking a dance career. There will be two rounds of competition choreographed by Galen Hooks one solo round and the second in pairs. 35 will become 16 and then 10 as dancers vie for a top spot on the show.
