The R-factor

With the conclusion of the Indian Puzzle Championship, I came across a very interesting trend. Take a look at the last 6 years Indian champions.



All winners' names start with the letter 'R'!

So, if your name starts with an 'R', you could be the next Indian champion. If your name doesn't start with an 'R', you could be the one to break this trend!
