If you've been around the internet you know all about Captcha's. This mod adds them to Minecraft!
By default the mod will require the user to finish a Captcha to continue doing what they were doing. The default cooldown between Captcha requests is 15 minutes.
Currently you can experience the following Captcha types using the mod:
- I'm not a monster (Where you have to prove you're not a monster by clicking the checkbox)
- Math question (Where you have to answer a math question)
But that's not all! The latest update brings even more excitement with new additions:
- Text Captcha: Transcribe distorted or obscured text to prove your observation skills.
- Image Captcha: Identify and select correct objects or patterns in images to demonstrate your visual perception.
The "Captcha" mod also provides config options for fine-tuning the gameplay experience. With options such as:
- gracePeriod - Set the duration of uninterrupted gameplay before Captcha challenges begin.
- captchaTime - Adjust the time limit for solving each Captcha challenge.
- captchaCooldown - Define the interval between successive Captcha requests.
