Why I am getting already asked questions in play?

Answer 1

Talking about the questions in challenges. some of them are repeatedly asked in other plays.

Answer 2

Yes that can happen if you are playing often

Answer 3

Because otherwise we couldn't answer every HTML question a million times meaninglessly and would be stuck at level 16 forever.

EDIT: Downvote? Yeah I know, the truth hurts...

Answer 4

According to my experience..u will get the same questions only when u play the challenges continuously.If u take time and play again they won't repeat
