In tic-tac-toe, given the following information, what is the best possible cell for the player to choose?

Question

Consider that the coordinates of the board are laid out like this:

1 2 3
4 5 6
7 8 9

Game A: X uses cell 1, then O uses cell 5. Which cell should X use next?

Game B: X uses cell 4, which cell should O use?

Game C: X uses cell 1, then O uses cell 9, which cell should X use next?

Answer 1

A : 9 - unless O then takes an even cell X can then play either 3 or 7 to clinch a win.

B : 5 - you can force a tie easily from that position

C : 7 - O is forced to play 4, then X plays 3 to clinch a win at that point.

Answer 2

Game A: Cell 9 is the best answer

Game B: Cell 5 is the best answer

Game C: Cell 3 is the best choice; then O NEEDS to choose 2; then X chooses 7; at this point you can win by choosing 4 or 5, and O can only block one

Answer 3

game a- cell 3 or 7

game b- cell 9 or 3

game c- cell 3 or 7

Answer 4

Game A: cell 9

Game B: cell 5

Game C: cell 7

Answer 5

Well,it depends.It depends on your strategy.Are you trying to block the opponent?Are you focusing more on offense?(What am I saying?!)Try giving more moves/information (if you only need ONE cell)because cells 2,3,4 and 7 are good for game A.In game B: almost all of them are alright.And in game C:well....maybe X should think......then go for any cell except cell 8 and 6.(I think)I just answered this for the points...hehehehe....I also wanted to share my knowledge. :)

Answer 6

game a:cell 3, game b: cell 1, game c:cell 3

Answer 7

WOPR: (From "WarGames") "a strange game. the only winning move is...not to play"

granted, the WOPR was referring to the game "Global Thermonuclear Warfare," but the remark applies to tic-tac-toe as well, despite the numerous incarnations of tic-tac-toe that showed up as gameshows on tv...(Hollywood Squares with Paul Lynde* in the center square, TicTac Dough, New Hollywood Squares with Whoopi Goldberg in the center square)

*p.s. ask your mom or dad who Paul Lynde was

Answer 8

game a -9,this would prevent x from creating a two way trap
game b -3? needs more in formation
game c-5 then if possible 7 to create a two way trap

Answer 9

game A use cell 3

game B use cell 9

game C use cell 2

Answer 10

In Game A: 5
In Game B: 5
In Game C: 7
