PuzzleCaptcha — Image Puzzle Captcha for Rust 1.0.0

A captcha system that triggers on player connect. Instead of a boring text input, players must solve a visual puzzle — reassemble a scrambled 3×3 image to prove they're human.

Works on Carbon. Drop your own PNG images into the data folder and the plugin handles the rest — slices them into pieces, shuffles them, and presents the puzzle in a clean fullscreen UI.
