## Overview

#### Purpose and entry point
This is a standalone interactive Python Tic-Tac-Toe game with a graphical click-based interface, match-result display, replay behavior, and persistent-in-session score tracking. The executable entry point is `main.py`.

#### Application runtime
The game runs as a local Python process launched with `python main.py`. No server, package manifest, database, API integration, or deployment infrastructure is present in the repository tree. The UI implementation and game logic are therefore expected to be coupled within `main.py`.

#### Game interaction loop
`main.py` is the primary control boundary: it initializes the game interface, receives board-cell click input, applies moves for alternating players, redraws or updates the board, and continues until a terminal outcome is reached. Player X is the initial player for each game.

#### Board and rule evaluation
The core domain stage is Tic-Tac-Toe state management: maintain the nine-cell grid, reject or ignore unavailable cells, alternate X/O turns, and evaluate rows, columns, and diagonals after moves. Terminal states are a win for either player or a completed draw. This logic resides in `main.py`.

#### Result and replay transition
After a terminal state, the application displays the outcome in a result screen or result mode. A subsequent click transitions back into a fresh playable board, rather than requiring process restart. This state transition is controlled by `main.py`.

#### Score tracking
The game maintains running player scores across replayed rounds during the same application session. Score presentation and score updates are part of the UI/game-state lifecycle in `main.py`; no repository evidence indicates durable storage between launches.

#### Assets and documentation
Visual examples are documentation assets rather than runtime architecture: `images/preview.gif` and `images/screenshot.png` demonstrate the expected UI. `README.md` provides launch and control instructions, while `docs/_config.yml` supports repository documentation publishing.
