SHALL WE PLAY A GAME?

Let's play tic tac toe!

Rules of play

A board had 9 squares (3 x 3). There are two players "X" and "O". "X" always goes first. Each turn, a player puts their mark in an open square. If a player can get three of their mark ("X" or "O") in a row (vertically, horizontally, or diagonally) they win.

We can represent the board with number 1 through 9.

  1 | 2 | 3 
 ---|---|---
  4 | 5 | 6 
 ---|---|---
  7 | 8 | 9

A game (in-progress or completed) can be represented as list of numbers for example:

# Empty board
[]

    |   |   
 ---|---|---
    |   |  
 ---|---|---
    |   | 

# One move
[3]

    |   | X 
 ---|---|---
    |   |  
 ---|---|---
    |   |   
  
 # Heated battle
[1,5,2,3,7,4,6]

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