This puzzle is inspired by DubiousMobius's Entropical Pairadise.

• Normal sudoku rules apply.
• Divide the grid into two orthogonally connected regions such that no 2x2 area is completely contained in a region. All cells in one region will have a value of 2D, where D is the digit on the cell, and all cells in the other region will have a value of -D.
• Two arrows of the same color on a cell with value N point to cells N steps away (negative values go in the opposite direction), one for each direction of the arrows, and those two values follow the corresponding rules:
  • Yellow (Sum): the sum of the values is equal to N.
  • Purple (Ratio): the values are in a 1:N ratio.
• Not all possible pairrows are given.
