Normal sudoku rules apply. Each line in the grid represents the path of a different rider. Riders earn 1 point for every odd digit on their path. A digit in a cell with a rider indicates the amount of points earned by that rider. The Red rider (R4C5) doesn't share a cell with its line. Stage Results: The Yellow rider scored more than the Green rider, who scored more than the Red rider, who scored more than the Teal rider. Two cells connected by a Yellow line must have a difference of at least 4. Two cells connected by a Green line must have a difference of at least 5. Adjacent digits along the red line have a different odd/even parity. Any set of three sequential cells along a dashed teal modular line contains one digit from (1,4,7), (2,5,8), and (3,6,9).
