Rules:
- There are four 3x3 regions of empty cells, which must be found by the solver. (shade these regions black)
- Each row and column contains the digits 1-9 once each.
- Each row and column also contains exactly 3 empty cells.
- (note that the non-empty cells are not divided up into boxes or regions)
- Extended 159:
- The non-empty cells in columns 1,5,9 are either indexes for the digit 1,5,9 respectively in the row, or they combine with non-empty cells in columns 2,6,10 respectively to create a sum which is the index for the 1,5,9 in the row.
- For example, if R5C1=7 and R5C2=3, then the 1 in row 5 can either go in R5C7 (indexed by the 7 only) or it can go in R5C10 (indexed by 7+3 = 10).
- A digit 1,5, or 9 in a row where C1,C5, or C9 respectively is an empty cell, need not be indexed.
- For example, if R5C9 is empty, then the 9 in R5 can go in any non-empty cell in the row.
- Numbered Rooms:
- The first non-empty cell seen by an outside clue gives the distance from the clue to the specified digit from the clue's side of the grid.
- Empty cells are counted as part of the distance, even if they are seen before the first non-empty cell.
- Black circles outside of the grid indicate that the digit contained by the first non-empty cell is the distance to one of the three empty cells in the row or column from the clue's side of the grid.

raised difficulty based on feedback about the break-in

Wow that's hard to break in, it flowed very well after the initial deductions were done though! Nice one.

added rule clarification (no regions for non-empty cells)
