Ellie was second to take on the cash builder but only answered one question correctly.
The Beast offered her £50 and £50,000 as her low and high offers, whilst being able to stick with £1,000 if she chose to do so.
She decided to take the low offer, telling host Bradley Walsh: “I want to get back, I’m going for the 50, 50 pounds.”
Mark agreed with her decision, saying: “If you get less than four in the cash-builder you should wipe the middle offer from your mind.
“Go high or go low in my opinion,” he added.
