Do You Like CAPTCHAs?

Evil Captcha adds 14 amusing CAPTCHAs to Minecraft that appear at the most inconvenient moments—for example, when opening a loot chest. The difficulty of CAPTCHAs gradually increases, and most have no maximum difficulty limit, so over time they can become almost impossible to complete.

This mod was created as a joke and is not a security system—just a small fun mechanic to diversify gameplay.

Mod Features

Various CAPTCHA Mini-Games

The mod offers many types of CAPTCHAs, each with unique mechanics:

• Classic Image Selection — need to select all areas containing a specific object. Difficulty affects required accuracy and available image pool.

• Multi-Images — several small pictures among which you need to find the correct ones. As difficulty increases, the number of images grows and animation slows down.

• Puzzle Slider — must move an image fragment to its proper place. Accuracy depends on difficulty level.

• Distorted Text — need to recognize increasingly obscured letters. Difficulty adds additional layers of distortion.

• Object Search — various items scattered over a background image, need to click on a specific one.

• Simple Comprehension Tests — objects with different attributes, need to choose the one matching the description (e.g., "green apple").

• Advanced Comprehension Tests — more complex tasks with multiple selection conditions.

• Math Problems — solving equations considering order of operations. Numbers and operators become more complex with higher levels.

• Find the Item — enhanced version of object search with huge number of elements on screen.

• Rorschach Test — interpretation of ink blots without difficulty influence.

• Slot Machines — need to reach a certain amount by playing slots. Can increase or decrease bets.

• Among Us — find the different image among identical ones.

• Catch the Wizard — quick reaction to moving target.

• Butterflies — need to click on all fluttering butterflies, whose speed increases with difficulty.

• Sponsor Message — message from sponsors.

• Journey of Slime — isometric mini-game in Frogger style with minecart and river obstacles.

Difficulty System

There is global and local difficulty. Global is shared among all players, while local increases with successful CAPTCHA completion. Final difficulty is calculated as global + local.

Configuration

• Lethal CAPTCHAs — limited number of attempts after which player dies
• Explosive CAPTCHAs — failure causes powerful explosion (works only with lethality enabled)
• Periodic Validation — random CAPTCHAs at certain time intervals
• Not Easy — excludes easy and unfailable CAPTCHAs
• Lives — attempts before death (3 by default)
• Time Intervals — settings for delays between CAPTCHAs
• Constant Difficulty Increase — global difficulty grows over time
• CAPTCHA Rewards — possibility to receive items for successful completion
• CAPTCHA Type Selection — can enable/disable specific mini-game types

Datapack Support

The mod supports creating custom CAPTCHA variants through datapacks. For unique images, a resourcepack is also required.

CAPTCHA Triggers

CAPTCHAs activate in the following situations:

• Joining a world
• Respawning after death
• Opening previously unopened loot chest
• Mining ores (probability depends on ore rarity)
• Periodic validation (if enabled)
