Normal sudoku rules apply.

Draw three snakes in the grid. Snakes starts and ends on grey Even squares and or grey Odd circles. Snakes move orthogonally and cannot touch themselves, not even diagonally. Snakes do not cross or intersect.

All given digits MUST be consumed by snakes.

A digit in a white square counts how many cells of the same snake color it can see vertically.

All counts are including itself. Other snakes block the view for these counts.

Digits separated by a white dot are consecutive and exactly one digit on each white dot is on a snake.

Digits separated by a black dot are in a ratio 1:2 and MUST be intirely consumed by snakes.
