Ooh tricky. I keep accidentally giving a valid answer rather than the invalid one

Yeah, I felt they’d be too easy, so I flipped it.

Quite difficult, I even have a lot of quizzes that are wrong answer only and I started trying to answer them correctly halfway through.

Sorry if I'm mistaken or I misread but for the third prompt shouldn't 15 work? 1+5 = 6

Edit: 79 works for that one

It's wrong answers only, so for the 3rd prompt you actually need the digits to add up to 16+. That's why 79 works.

Sum of digits less than 16

50 should work right?

Tricky. You might want to mention that a mistake ends the quiz.

Nice quiz, ty!

However when you ask for a "Factor of 100" the answer 33 is not accepted, even if it's wrong.

I couldn't figure out what you were looking for on the 3rd prompt. I read "Sum of digits less than 16" as "Sum of digits that are less than 16".

Maybe modify that to read, "Sum of digits is less than 16"?
