• Normal 6 by 6 sudoku rules apply.
• Common line:
  • a) Any two lines have at most one type of digit in common. Digits on a line are allowed to repeat. E.g.: If a line 'A' contains 1,1,2,4, and a line 'B' contains 2,4,5,6, that is not allowed, because both the 2 and 4 are shared. However, if line 'A' was again 1,1,2,4, and line 'B' instead contained 1,1,5,6, that would be allowed, since only the 1 is shared by both lines. (The fact that the 1 appears twice is irrelevant for this rule.)
  • b) Within a single line, more common digits have lower value. E.g. if a line contains the digit X three times, the digit Y two times, and the digit Z once, then it must hold that X<Y<Z. (If two digits appear an equal number of times, either might be smaller.)
