Duplicates (Compass Copies #5)

- Standard Sudoku and Kropki Pair Rules Apply
- Compass Cells
- Each Compass cell points to a target cell. In the Compass Cell, the direction to the target cell is given by a compass heading (north, south, etc., or ?? if the solver must determine the direction) and the distance, in cells away from the target, is given by the digit.
All restricting attributes (i.e., kropki dots) — if any — on a Compass Cell are copied onto its target cell. Similarly, all attributes of a target cell are also copied back onto its Compass Cell. This means that in the finished puzzle, every target cell will have the exact same restrictions — or lack of restrictions — as its compass cell has. - EXAMPLE
- Suppose R1C1 is a Compass Cell marked with SE (south-east) and contains the digit 3. This points to R4C4, being three cells south-east of R1C1, so in the finished puzzle, R1C1 and R4C4 will both have the exact same configuration of kropki dots on their edges.
- NOTES
- FIRST, there is no negative constraint. In the finished puzzle, there may be many places where cell restrictions could be placed, but have not been.
SECOND, in the finished puzzle, every drawn dot will be a copy (perhaps of a copy of a copy...) of one of the dots that are initially on the grid. During the solve, no "new" dots should ever be introduced simply due to numerical relationships that a digit might have with the digit in any neighboring square.
THIRD, the digit in a Compass Cell is limited to the distance to the edge of the grid. So if R5C5 is a compass cell, it can only contain 1-4. Furthermore, since Kropki dots cannot be placed on the outer edge of the grid, this means that if R1C2 were a Compass Cell with a dot on its left-hand edge, it could not possibly have the direction West or Southwest. - Solve Online
