Welcome to a puzzle that combines the logic of arrows with the charm of Cupid! This Irregular Cupid Sudoku is a unique variant that I created for practice for the Italian round of the Sudoku Grand Prix Championship 2013. The puzzle uses a classic 9x9 grid but divides it into irregular, jigsaw-like regions instead of standard 3x3 boxes. On top of this, it features Cupid's arrows. The rule is that an arrow starting from a cell indicates the digit in that cell is repeated at least once somewhere in the direction the arrow points.
This is my 71st contribution to the Daily Sudoku League, and I've designed the puzzle to follow a logical path where almost every arrow must be used to find the solution. To fit the theme, I also arranged the given hints in a heart shape. This puzzle offers a rich and satisfying challenge, perfect for solvers looking to explore a less common variant with a thematic touch.
Rules of the Irregular Cupid Sudoku
Classic Sudoku Rules apply. Additionally, an arrow starting from a cell indicates that the digit contained in this cell is repeated at least once in the direction of the arrow.

The 5 and 6 in rows 3 and 4 could go either way.
No, it cannot be replaced. If replaced then 6 will come on arrow and the Cupid Sudoku rule will break.
