Variant g applies to Type 6 cancels and indicates that there is a numeral within a circular region in the killer grid. [Curator Note:] This definition is not quite true in practice. A g variant seems to indicate that there is a circular region in the center of the grid that may or may not contain a numeral. If a numeral exists, then the -1 variant is added.

There is no special variant code for a Type 6 grid with the numeral inside a circle inside the circular region. By the way, it is the cancel that is blurry – not the scan.
