Rules:
Place the digits 1-9 once each into each row, column, and box within the main 9x9 grid.
Numbered Rooms:
Place a digit into every cell outside the grid. A digit outside a row or column is placed into the Nth cell in that row or column, where N is the first digit in that row or column.
Bounce Lines:
A digit N on a line is consecutive with at least one digit that is N steps away from it along the line.
For example, 231224 would be a valid line.
Have fun solving!
