When I started creating puzzles and Sudoku around 10 years back the main aim was to create a puzzle for an experienced player that will take around 1 minute to solve it. At that time I never tried to create a symmetrical Sudoku or puzzle. Later slowly symmetry started becoming part of my Sudoku creation but at that time I never thought of creating a themed Sudoku. However for the last year, whenever I create a Sudoku puzzle I will try to think of a theme for that Sudoku and then create it so that aesthetically it looks great.  For the last year, I have created many Arrow Sudoku-themed puzzles for a US-based magazine. Even though I have not posted many of the Arrow Sudoku puzzles on this blog till now. From now onward, I am planning to post these themed Arrow Sudoku puzzles on this blog.
Today's  Arrow Sudoku puzzle is themed TWIN. Word TWIN is made using the Pentomino shapes T, W, I, and N. Each of these letters which are put on the four corners further divided into two arrows which are overlapping with each other. The Center part of the Sudoku contains pair of two twin arrows that are similar in look. I created this Arrow Sudoku puzzle thinking of this theme. However, to most of the audience, this theme may not be clear immediately as in many countries Pentomino sets are not used prominently. Anyway, this is my first and maybe last puzzle that I tried to make with Pentominoes. Later I decided to create puzzles that are visually appealing and these puzzles I will be posting later.
Today's Arrow Sudoku puzzle is having an interesting opening. Getting started will be tough but once a few digits are entered, then the Sudoku can be completed very fast. This is tough Sudoku and an experienced player should take more than 6 minutes to solve this Sudoku puzzle.
Meanwhile, I am posting this Arrow Sudoku puzzle in the Fun With Sudoku Series as the 221st Sudoku puzzle in this series.
