The player whose turn is first has the choice to mark  X or  O   to one of the nine squares , Here we choose X for first player .
Second player then mark its symbol  O in the remaining 8 squares
The thumb of the rule is to make the three successive square grids of the same sign , it does not matter whether they are horizontal , vertical or diagonal , they just need to be three consecutive squares filled with same symbol X or O.

                   if true
                             Player with that mark Wins and Stop
           3.2  Is there any three horizontal grids with same Mark (i.e X or O)
                   if true
                             Player with that mark Wins and Stop
