개요
Tic-Tac-Toe (also called Noughts and Crosses or X's and O's) is a simple paper-and-pencil game for two players. Despite being trivial to master, it remains popular as a teaching tool and children's game.
설정
Draw a 3x3 grid. One player uses X, the other uses O. X traditionally goes first.
플레이 방법
- Players take turns placing their mark (X or O) in an empty cell.
- Once placed, marks cannot be moved or removed.
- The first player to get three marks in a row wins.
- Rows can be horizontal, vertical, or diagonal (8 possible winning lines).
- If all nine cells are filled with no winner, the game is a draw (cat's game).
게임 승리
Win by placing three of your marks in any straight line (row, column, or diagonal). The game draws if all cells fill without a winner.
전략 팁
If you go first (X), play in a corner - it gives the most winning opportunities.
If opponent starts in the center, play a corner to maximize your chances.
If opponent starts in a corner, play the center.
Always block when your opponent has two in a row (unless you can win).
Create a 'fork' (two ways to win) when possible - opponent can only block one.
With perfect play from both sides, the game always ends in a draw.
역사
Tic-Tac-Toe dates back to ancient Egypt. Similar games were played in Rome (Terni Lapilli) and medieval Europe. It's been 'solved' - perfect play always leads to a draw.
