Hi all. It really feels great to reach 500 Sudokus on my blog. When I started the blog, I never imagined I would come this far. To celebrate this milestone, I am offering a discount of 20% on pdf copies of all books available on payhip. Here is the link  https://payhip.com/worldofsudoku 

Rules: Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and 3x3 outlined box. 

There are some arrow shapes in the grid. The sum of the digits along the path of each arrow must equal the digit in the circled cell. Digits may repeat along an arrow. 

Clues outside the grid represent the sums of the digits sandwiched between the 1 and the 9 in that row or column.  

A black dot between two digits means one of them is double the other. Not all possible black dots are necessarily given.
