WORLD OF SUDOKU VOL #1 - Updates


 

   Hello Friends. I have a wonderful news to share with you all. My first book World Of Sudoku Vol # 1 is now available as paperback on the Amazon store. The last 3-4 days have been full of anxiety. First, Amazon no longer accepts puzzle books in e-book format. I had spent so much time and effort in formatting and other stuffs for e-book format. It was disheartening when I got the mail stating that puzzle books are no longer accepted as e-books. Also, they have strict guidelines regarding the cover pages as well as interior formatting for paperback. On the third attempt, after formatting the book , it finally got accepted as paperback and is now available to purchase. The link for the book is here

   The book for the Indian market will also be available soon ( around 7-8 days from now ). I will be sharing the details soon.
