Made a game out of something me and my friends play

Hello everyone, I made a webgame out of a game me and my friends usually play during car rides and other times where we have a lot of time on our hands.

The goal is to figure out who the person the leader is thinking about, by asking 10 YES/NO questions.

I have a daily challenge that you can test here:
Daily Challenge — WhoInTen

But its also possible to create your own custom game where you select the person and can challenge your friends.

Would love feedback on how i can improve any part of it.
