About this app

Tic-tac-toe (American English), noughts and crosses (Commonwealth English and British English), or Xs and Os/“X’y O’sies” (Ireland), is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a diagonal, horizontal, or vertical row is the winner. It is a solved game with a forced draw assuming best play from both players.

Tic-Tac-Toe game on a console application in which 2 players could play against each other, this will be achieved through applying and practicing many concepts of programming which programmers use all the time through their programming careers such as advanced if statements,
advanced arithmetic operations, loops, Arrays, and 2D arrays. Tic-tac-toe is a game that is traditionally played by being drawn on paper, and it can be played on a computer or on a variety of media. Other games, such as Connect 4, are based on this classic. A relatively simple game usually played on a grid of 3-by-3 squares, tic-tac-toe is mainly enjoyed by children. Tic-tac-toe can be made significantly more complex by increasing the size of the board to 4-by-4, 5-by-5, or even up to a 20-by-20 grid. The goal of tic-tac-toe is to be the first player to get three in a row on a 3-by-3 grid or four in a row in a 4-by-4 grid.

To start, one player draws a board, creating a grid of squares, usually 3-by-3 or 4-by-4.In a 3-by-3 grid game, the player who is playing "X" always goes first. Players alternate placing Xs and Os on the board until either player has three in a row, horizontally, vertically, or diagonally or until all squares on the grid are filled. If a player is able to draw three Xs or three Os in a row, then that player wins. If all squares are filled and neither player has made a complete row of Xs or Os, then the game is a draw.

One of the game's best strategies involves creating a "fork," which is placing your mark in such a way that you have the opportunity to win two ways on your next turn. Your opponent can only block one, thereby, you can win after that.

The gameplay is the same if you are playing on a 4-by-4 grid. The "X" player goes first. And, players alternate placing Xs and Os on the board until a row is completed horizontally, vertically, or diagonally, or all 16 squares are filled. If all 16 squares are filled and neither player has four in a row, the game is a draw.

Win: If the player has two in a row, they can place a third to get three in a row.
Block: If the opponent has two in a row, the player must play the third themselves to block the opponent.
Fork: Create an opportunity where the player has two ways to win (two non-blocked lines of 2).
Blocking an opponent's fork: If there is only one possible fork for the opponent, the player should block it. Otherwise, the player should block all forks in any way that simultaneously allows them to create two in a row. Otherwise, the player should create a two in a row to force the opponent into defending, as long as it doesn't result in them creating a fork. For example, if "X" has two opposite corners and "O" has the center, "O" must not play a corner move in order to win. (Playing a corner move in this scenario creates a fork for "X" to win.)
Center: A player marks the center. (If it is the first move of the game, playing a corner move gives the second player more opportunities to make a mistake and may therefore be the better choice; however, it makes no difference between perfect players.)
Opposite corner: If the opponent is in the corner, the player plays the opposite corner.
Empty corner: The player plays in a corner square.
Empty side: The player plays in a middle square on any of the 4 sides.
