  REQ: Is it possible to post these puzzles in a format where the puzzle can be filled in online? Alternatively, is it possible to offer this as downloadable and editable excel file?

  Hi Puneet,
  I am trying to cover as many different variations as possible, so it is very difficult to make the format for online solving. I tried for Sudoku but it took lot of time for writing the Sudoku Applet and still it is not in working condition. If I put the puzzles as editable excel file then puzzle will not be visible here and most of the people will not be able to see the puzzle if they don't have MS excel.

  Loving this variant Rajesh.
  
  About the your comment and the comment by Puneet, one option you could use is Google Docs. You could post both an image copy of the puzzle as well as a Google Docs version with a spreadsheet that can be tried online. Just a thought.

  Thanks Puneet an David for your suggestions. I will definitely look to put xls file of the puzzle in future so that one can download and try solving it without taking the printout.
  
  Google docs share again if I give edit rights, then puzzle will not be same after some time as if one person changes, the change will be visible to others.
  
  Looking forward for more such suggestions.
