Normal sudoku rules apply.

Shade cells using two colours such that each colour forms an orthogonally connected region, and no 2x2 area is a single colour.

A digit in a cell with arrows must match the total count of cells of the opposite colour in all given directions. For example, a 7 in a cell with arrows pointing east and south might be counting 4 cells to the south and 3 to the east. Every arrow points to at least one cell of the opposite colour.
