  • Killer cages
  • Little killers

The brief

Standard sudoku rules apply. Cells within a cage must sum to the number in the top left corner of the cage. Cells along a diagonal indicated by an arrow outside the grid must sum to the number by the arrow. The red line is an anti-palindrome line: cells equidistant from opposite ends must sum to 10.
