Answer 2

Tic-Tac-Toe is a simple game for 2 players.
It has a 3×3 grid.

One player starts the game by drawing an ❌ on any slot in the grid.
Then is opponent's turn to draw a ⭕ in any slot in the grid (except the slot that already has an ❌ on it).
Then is again the first player's turn, who will again put an ❌ in any slot in the grid (except the grid that already has an ❌ or a ⭕ on it).
This will continue until the grid is either full or until one of the players has already won the game.

You can win the game by getting 3 of your marks in the same row as upwards, sidewards or diagonal, before your opponent does it.
