Catherine Wheel Sudoku
(Published on 3. February 2021, 19:17 by steelwool)
There are 4 outer corners to the board.
At each of the 4 outer corners, there are 4 cells forming a square.
Starting at ONE of the four cells, it is possible to visit each of the other three cells in the corner in turn, by orthogonal moves, such that the ratio between the adjacent numbers is 1:2 or 1:3.
In the centre box, none of the 9 digits is connected orthogonally to another such that the ratio is 1:2 or 1:3.
Normal sudoku rules apply. Cages do not contain repeated digits. Little killer diagonals may include repeated digits.
The colour on the board is cosmetic.
