Teams compete to navigate rooms flooded with lava by leaping from chairs, hanging from curtains and swinging from chandeliers.
There won't be a season 4, the show has ended.
Teams enter the lava-filled courses with confidence and bravado. But after navigating the slippery obstacles, that's rarely how they exit.
The obstacles have changed but don't worry — the floor is just as red and bubbly as you remember. New this season: a very slippery volcano.
It's the "Nailed It!" holiday special you've been waiting for, with missing ingredients, impossible asks and desserts that look delightfully sad.
