What's a flawless victory?

Question

I got a badge for 5 flawless victories in a row, but most certainly don't have 5 consecutive 5:X wins. What is going on here?

Answer 1

Flawless victories are those challenge wins in which u score 5 out of 5 and win the challenge

Answer 2

If that's the case, then the detection for the badge works in mysterious ways.

Answer 3

I think a flawless victory is one where you never get a wrong answer in which your opponent gets that one correct. For example if you win 4 to 3 but the question that you got wrong your opponent also got wrong then it would still be considered a flawless victory. I think thats how it works.
