Tic Tac Toe classic from boar

Tic-tac-toe, also known as noughts and crosses or Xs and Os, is a classic two-player strategy board game. The game is typically played on a 3x3 grid, although variations with larger grids are possible. Here's a description of the basic elements and rules of tic-tac-toe:

**Components:**
1. **Game Grid:** The game is played on a 3x3 square grid, which consists of nine empty cells arranged in three rows and three columns.

2. **Markers:** Two players participate in the game, usually denoted as "Player X" and "Player O." Each player uses their own distinct marker. Player X often uses "X," while Player O uses "O." These markers are used to claim cells on the grid.

**Objective:**
The objective of tic-tac-toe is to be the first player to form a line of three of their markers horizontally, vertically, or diagonally on the game grid.

**Gameplay:**
Players take turns to make their moves. The game proceeds as follows:

1. **Player X Starts:** Player X makes the first move by placing their marker ("X") in any empty cell on the grid.

2. **Player O's Turn:** Player O then places their marker ("O") in an empty cell.

3. **Alternate Turns:** Players continue taking turns, one at a time, until one of the following conditions is met:
- A player forms a line of three of their markers either horizontally, vertically, or diagonally, and they win the game.
- The entire grid is filled with markers, and the game ends in a draw (also known as a "cat's game" or "stalemate").

**Winning and Ending the Game:**
The game can end in one of three ways:

1. **Player X Wins:** Player X forms a line of three "X" markers, either horizontally, vertically, or diagonally.

2. **Player O Wins:** Player O forms a line of three "O" markers, either horizontally, vertically, or diagonally.

3. **Draw:** If all nine cells on the grid are filled, and neither player has formed a winning line, the game ends in a draw, and no one wins.

**Strategy:**
Tic-tac-toe is a simple game with a finite number of possible moves. With perfect play, the game will always end in a draw. However, players can aim to block their opponent from forming a winning line while trying to create their own opportunities to win.

Tic-tac-toe is often used as a teaching tool for basic strategy and critical thinking. It's easy to learn and provides a foundation for more complex board games.
In summary, tic-tac-toe is a straightforward yet engaging game played on a 3x3 grid where two players take turns placing their markers in empty cells. The goal is to be the first to form a line of three markers in any direction while preventing your opponent from doing the same. The game ends in a win for one player, a draw, or a stalemate.
