Normal sudoku rules apply. Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Prime digits (2,3,5,7) must NOT be orthogonally adjacent to each other. Square roots with single digit perfect squares MUST be orthogonally adjacent to their square. (all 2’s must be adjacent to a 4, and all 3’s must be adjacent to a 9).
