ocular color sensors. on go, your chair will begin to spin and a color sequence will play on the displays in my operating system. the colors i need to learn our red, green, yellow, and blue. your job is to remember the sequence. when your chair stops, you will have 30 seconds to replicate this sequence using the color buttons in the room. it is imperative that you get the sequence right to help my sensors activate. i will award the player with the longest correct sequence in the fastest amount of time a game changing secret power. the downgrade competition is called fear face. and here's how it works. i'm intrigued by human fear and want to learn about all variations of this emotion.

on go, you will stick your head into one of my four fear boxes. inside, something terrifying awaits along with the letters of a scrambled word that matches an emotion tile inside the room. once you identify all the letters, exit the box and find the tile that matches the scrambled word. then label the box with the correct emotion and move on. once you have placed all four tiles, plug the cord into my mainframe and hit your button to lock in your answer. you will have a maximum of 90 seconds to finish. the player with the fewest correctly labeled boxes in the slowest time will be in last place, and will have their game severely downgraded. you won't know if you have been upgraded or downgraded until after the other eight houseguests have joined the game. >> julie: thank you, ainsley.

all right, get ready, houseguests. i will be back for your first competition before you know it. up next, two competitions play out. which houseguest will have their game upgraded and which will have their game downgraded? find out when we return. stay with us.
