PUZZLE NO. 128 : Answer 8 Sudoku



RULES : Classic sudoku rules apply. Circled 8s between two orthogonally ( horizontally or vertically ) adjacent cells imply that one of the four binary operations ( addtion , subtraction, multiplication or division ) on the marked cells result in an 8. If there is no circled 8 between two orthogonally adjacent cells, 8 cannot be produced by the two digits going through any of the four binary operations.

  4. 7:00 Good use of converse constraints. This type also exists in argio-logic as Sudoku N.
