Tik Tak Toe

One of the players plays with "crosses", the second - with "noes".

Rules of the game
Winning game of tic-tac-toe
Players take turns putting 3×3 signs on the free cells of the field (one is always crosses, the other is always zeros). The first one to line up 3 of their pieces vertically, horizontally or diagonally wins. The first move is made by the player placing crosses.
Usually, at the end of the game, the winning side crosses out with a line its three characters (zero or cross), which make up a continuous row.
Analysis
Algorithms are well-known for each of the parties, which guarantee a draw in any game of the opponent, and if he makes a mistake, they allow you to win. Thus, the game is in a state of "no man's death".
Below are some of these strategies. It is believed that the player always respects two rules that take precedence over all others:

Rule 1. If a player can win immediately, he does so.
Rule 2. If a player cannot immediately win, but his opponent could immediately win by making a move to a square, the player himself makes a move to that square, preventing an immediate loss.
