Rules:

Normal sudoku rules apply. Given two cells which both contain the digit N, the Euclidean distance between (the centres of) those cells must be at least √N times the sidelength of a single cell. In other words, if moving from one such cell to the other takes X horizontal steps and Y  vertical steps, then √(X^2 + Y^2) ≥ √N.
