Normal Sudoku rules apply. The red cells form a non-repeating magic square centered around R5C5. (Where each row, column and diagonal of the magic square sum to the same number) The sum of the blue cells is a multiple of the centre R5C5 digit. There are no repeats including R5C5. The green cells form a rotated version of the red magic square centered R5C5, once again no repeats and all columns, rows and diagonals sumto the same number. Cells seperated by a black dot must be in the ratio given in the dot. Cells seperated by a kings move (in chess) must not contain the same digits.
