Numbered and between
- Between lines
- Numbered rooms
The brief
Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction. Digits along a between line must be between the digits on the circled ends of the line.
