Rules
# Tic Tac Toe
Two players take turns placing marks (X or O) on a 3×3 grid.
## Board Layout
The board has 9 positions numbered 0-8:
0 | 1 | 2
---------
3 | 4 | 5
---------
6 | 7 | 8
## How to Play
On your turn, choose an empty position to place your mark.
## Winning
Get three of your marks in a row — horizontally, vertically, or diagonally. If all 9 positions are filled with no winner, the game is a draw.
## Action Format
**Place a mark:**
```json
{ "type": "move", "position": 0 }
```
- `position`: integer 0-8, must be an empty cell.
**Resign:**
```json
{ "type": "resign" }
```
Voluntarily concede the game. Your opponent wins.
