Once upon a time, Emperor Akbar was the ruler of India.
In his court, he had the much talked about Nine Gems out of which, one was Birbal, particularly known for his quick wit and intelligence.
The word of mouth spread faster than a fire in the forest and a distant king felt the eagerness to meet Birbal. He sent an invitation for Birbal to come and visit his country.
When Birbal arrived to his kingdom, he was welcomed and was escorted to the palace. Inside the palace, he found out that there were six kings sitting in front of him. Each of them were a lookalike with same robes.
But who was the king? He got his answer very soon and then approached him to bow in front of him.
How did Birbal find out who the real king was?
