Let's Get There Sloooowly
- Little killers
The brief
- Normal sudoku rules apply, i.e. each Row, Column, and 3x3 region has to contain the digits from 1 to 9 once each.
- Regionometer: Box borders divide the blue line into segments whose sums must strictly decrease from one end to the other. If the line enters a box more than once, each segment is considered separately. (In which direction it decreases is to be determined by the solver.)
- Little killer: Digits on a marked diagonal must sum to the clue outside the grid. (If there is no conflict with other rules, digits on such a diagonal may repeat.)
