Thank you for the valuable suggestions.
A number of visitors to the site have suggested that puzzles be posted before the hint & solution are posted.
In light of this , I have created this section titled "Upcoming Puzzles". You may attempt to solve these puzzles.
With in a month of posting these puzzles, I will post the hint and solution for these puzzles and move them one by one to the home page.
This is a sort of home work for viewers 
Good luck taking your brains for a spin!
