Normal sudoku rules apply. Cells marked with a circle contain an odd digit; cells marked with a square contain an even digit. Two neighbouring digits along a green line have a difference of at least 5. You must put this pattern of clues into the grid 7 times: □ ⟋ □ ⟋ 5 ○ □ ○ ○ The patterns may overlap with each other or the given clues. If there is an overlap all clues must still be valid. Digits may repeat within a pattern. You may not rotate or mirror the pattern or put it partially off the grid.
