## Overview

This is a small browser-based Tic-Tac-Toe game. A player clicks a cell; the JavaScript records the mark, checks for a win or tie, and updates the displayed result. The reset button clears the board and restores the starting state. The source excerpt shows these DOM interactions and rules; the HTML and CSS files are present in the tree, but their contents were not sampled.

Main entry points: [`js/index.js`](https://github.com/facundodlf/tic-tac-toe/blob/main/js/index.js) (Game logic), [`index.html`](https://github.com/facundodlf/tic-tac-toe/blob/main/index.html) (Game board)
