It utilizes image rotation as a challenge for the user to solve.\n\n\u003cp align=\"center\"\u003e\n  \u003cimg src=\"https://cdn.discordapp.com/attachments/551050418541821992/1176259452786180127/lg.png?ex=656e37fb\u0026is=655bc2fb\u0026hm=9a6f3d9e1548cac5a5cf603b123704d52ed194c2f5846d496f57dea1b713ae74\u0026\" alt=\"AirBnB Clone Logo\" width=\"500\"\u003e\n\u003c/p\u003e\n\n## Features\n\n- **Image Rotation Challenge:** Users are presented with an image that needs to be rotated to the correct orientation.\n- **Random Image Selection:** The system randomly selects a set of images for each challenge to enhance security.\n- **Dynamic Image Rotation:** The rotation angle of the image is set randomly, increasing the variability of challenges.\n\n## Project Structure\n\nThe project consists of the following files:\n\n- **index.html:** The main HTML file that contains the structure of the Numcha CAPTCHA system.\n- **styles.css:** The stylesheet file defining the visual appearance of the CAPTCHA system.\n- **numcha.js:** The JavaScript file containing the logic for generating and verifying CAPTCHA challenges.\n\n## Getting Started\n\n1. Clone the repository to your local machine.\n   ```bash\n   git clone https://github.com/MinightDev/Numcha.git\n   ```\n\n2. Open the `index.html` file in a web browser to see the Numcha CAPTCHA system in action.\n\n## Usage\n\n- Click the CAPTCHA start button to initiate the challenge.\n- Rotate the presented image until it's correctly oriented.\n- Click the submit button to verify your response.\n- The system provides feedback on whether the CAPTCHA was successfully solved or not.\n\n## Customization\n\nYou can customize the CAPTCHA system by modifying the following parameters in the `numcha.js` file:\n\n- **maxImages:** Controls the maximum number of images in a challenge.\n- **imageUrls:** Array of URLs for the challenge images. Add or remove URLs to change the image set.\n\n## Contributing\n\nContributions are welcome!
