What constitutes the top of a Tic Tac Toe recreation?

Tic Tac Toe is famously a futile recreation, as a result of when each side play optimally, it all the time ends in a draw.

Curiously now, a good friend of mine (let’s name her Alice) performed Tic Tac Toe with one other good friend (let’s name him Bob).

The sport went as follows:

X: Bob
O: Alice

Transfer #1                 Transfer #2

     |     |                 |     |     
  X  |  -  |  -           X  |  O  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  -  |  -  |  -           -  |  -  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  -  |  -  |  -           -  |  -  |  -  
     |     |                 |     |     

Transfer #3                 Transfer #4
     |     |                 |     |     
  X  |  O  |  -           X  |  O  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  X  |  -  |  -           X  |  O  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  -  |  -  |  -           -  |  -  |  -  
     |     |                 |     |     

Transfer #5                 Transfer #6
     |     |                 |     |     
  X  |  O  |  -           X  |  O  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  X  |  O  |  -           X  |  O  |  -  
_____|_____|_____       _____|_____|_____
     |     |                 |     |     
  X  |  -  |  -           X  |  O  |  -  
     |     |                 |     |          

The issue is:

• Bob maintains he gained, as a result of after transfer #5, he had three X in a row
• Alice maintains it is a draw, as a result of after transfer #6, each had three X or O in a row
• Bob argues that the winner is who will get there first
• Alice argues that because the second participant she’s owed a 3rd flip to have the identical variety of turns, resulting in a draw

This grew to become a sizzling debate throughout a night with a number of different associates, the place we found that individuals from completely different nations remembered completely different guidelines from their childhood.

Curiously, guidelines on-line appear inconclusive. It often says the winner is the one who will get three in a row, however it does not clearly specify when the sport ends. A minimum of one reference talked about that the sport ends when all 9 locations of the board are crammed.

Folks of the web, please repair this problem as soon as and for all.
