The first grand tour of cycling is upon us, The 2025 Giro d'italia starts today (Friday), and I made a puzzle to celebrate it. Enjoy the ride!

You can try my Tour de France and Vuelta a España puzzles from last year here: TDF Stage 1, La Vuelta Stage 1

Solve online: SudokuPad

Rules:

Normal sudoku rules apply. Place the digits 1 to 9 in each Row, Column, and 3X3 box.

Renban: Digits on a purple line must form a set of non-repeating consecutive digits in any order.

Entropy line: Each set of three consecutive digits on a Peach entropy line has to contain a low (1,2,3), a medium (4,5,6), and a high digit (7,8,9).

Region Sums Line: Box borders divide the blue line into segments with the same sum.

Zipper line: Digits an equal distance from the center of a lavender 'Zipper Line' sum to the digit in the middle of that line.

Stage Rules: Each line in the grid represents the path of a different rider. Each rider earns points differently.
- Pink Rider (Renban): Earns 1 point for every digit that is in its correct position starting from r3c1 (1 in r3c1, 2 in r3c2, etc.).
- Peach Rider (Entropy): Earns 1 point for every Odd digit (1,3,5,7,9) along its path.
- Blue Rider (Region Sums): Earns 1 point for every even digit (2,4,6,8) along its path.
- Lavender Rider (Zipper): Earns 1 point for every low digit (1,2,3,4) along its path.

Results: The Pink rider scored more than the Blue rider, who scored more than the Lavender rider, who scored more than the Peach rider.

Finally, Digit in a cell with a rider indicates the amount of points earned by that rider.
