What's the problem?

There are only two action balls: Al Shayeb and Al Malka.

Shayeb and Malka know the previous one, while
The rest of the citizens do not know it. Citizens should ask questions that answer yes or no only in order to try to discover the above.

Shayeb's mission is to answer questions without revealing the above directly.

The mission of Al-Malka is to help citizens
He should know the previous one and hint to them as much as possible, but without revealing that he is the one who is the one who is wrong.

At the end of the round, everyone votes on who they think is the one who they think is the one who is the winner. If the player survives the vote, he wins, and if he is revealed, he loses.
