Firing Across Borders
- Arrows
- Regions to construct
- Chaos construction
The brief
Divide the grid into seven regions of orthogonally connected cells. Fill the grid with the digits 1-7 so that no digits repeat in any row, column or region.
Digits along an arrow sum to the digit in the attached circle. An arrow's circle and its tip are always in different regions. Each region must contain exactly one circle and one arrow tip.
