  • Fog of war
  • Killer cages
  • Kropki dots
  • Negative constraint

The brief

  • Normal Sudoku rules apply.
  • 1-5-9: Each digit in column 1 indexes the 1 in its row (i.e if R3C1=4 then R3C4=1). The same rule applies to column 5 digits indexing 5 in its row, and column 9 digits indexing 9 in its row.
  • The digits in a cage must sum to the number printed in its corner. Digits may not repeat within a cage.
  • A black dot between cells indicates cell values with a 2:1 ratio.
  • ALL BLACK DOTS ARE SHOWN
  • The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell.
