Consecutive Sudoku is one of my favorite Sudoku type. In this Sudoku type, if two orthogonal numbers are consecutive to each then either a dot or line is given between these two numbers. One should always remember that Consecutive Sudoku puzzle is a converse rule Sudoku type. It means that in case there is no line or dot given between two orthogonal numbers, then these numbers cannot be consecutive to each other.
To solve Consecutive Sudoku, one technique which is very useful to solve a very tough Consecutive Sudoku puzzle is that one should keep track whether a cell will contain a Even number or an Odd number. It is because each line or dot will have one even and one odd number across it. Now if in any row/column or 3x3 there are 4 lines or dots are already given then remaining one cell will always contain a odd number. By this way one can reduce the possibilities for some of the cell which can lead to solution of very touch Sudoku puzzle.
