Key Features:

★ Interactive Gameplay: Users solve a simple yet engaging Tic-Tac-Toe challenge to prove they are human, replacing traditional CAPTCHA methods with a more enjoyable experience.
★ Randomized Starting Player: Alternates between the user ("X") and the computer ("O") as the starting player, adding an element of unpredictability to each session.
★ Unique Game States: Pre-fills 0–2 random moves on the board at the start of each game, creating dynamic and varied challenges for users.
★ Session-Based Validation: Each CAPTCHA session is tied to a unique session token, ensuring that responses cannot be reused or forged.
★ Timing Checks: Measures the time taken to complete the CAPTCHA and rejects submissions that are too fast (<2 seconds), deterring automated bots.
★ DOM Obfuscation: Uses dynamically generated IDs and event delegation to obscure the structure of the board, making it harder for bots to analyze and interact with the CAPTCHA programmatically.
★ Accessibility Support: Includes keyboard navigation, focus management, and ARIA attributes to ensure the CAPTCHA is usable for individuals with disabilities, including those using screen readers.
★ CSRF Protection: Integrates with Joomla's CSRF token system to safeguard against cross-site request forgery attacks.
