Half the truth
- Killer cages
- Arrows
- Little killers
The brief
- Normal 8x8 sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 8 once each.
- Killer cages: Digits in a cage sum to the clue in the top left.
- Little killers: Digits on a marked diagonal sum to the clue outside the grid. (If there is no conflict with other rules, digits on such a diagonal may repeat.)
- Arrows: Digits on an arrow sum to the digit in the circle from which the arrow emerges.
