Tic-Tac-Toe – A Classic Game.

The game’s grid markings have been found chalked all over Rome. Tic-tac-toe was also used by MIT students in the year of 1975, to signify the computational ability of Tinkertoy elements.
There are only 138 terminal board positions. This can be found out by the state of the board, and after taking into account board symmetries (i.e. rotations and reflections). Assuming that X makes the first move every time, there are:
- 91 distinct positions are won by (X)
- 44 distinct positions are won by (O)
- 3 distinct positions are drawn
The following list shows first available move, using which you can play a perfect game of tic-tac-toe. These turns were used in Newell and Simon’s 1972 tic-tac-toe program.
- Win: If you have two in a row, you can place a third to get three in a row.
- Block: If the opponent has two in a row, you must play the third yourself to block the opponent.
- Fork: In this case, you must create an opportunity where the player has two threats to win.
- Blocking an opponent’s fork:
Option 1: In order to force the opponent into defending, you should create two in a row. This is fine as long as it doesn’t result in them creating a fork.
Option 2: If there is a configuration where the opponent can fork, you should block that fork.
- Center: A player marks the center. Playing on a corner increases the chances of the other player to make a mistake and may, therefore, be the better choice. But it makes no difference between perfect players.
- Opposite corner: If the player 2 is playing in the corner, you must mark the opposite corner.
- Empty corner: You in a corner square.
- Empty side: You in a middle square on any of the 4 sides.
