## Description

**Real Code Breaker** is a classic mind game inspired by the board games Bulls & Cows, Numerello, and others. Your goal is to uncover a secret code by making guesses and analyzing the hints provided for each puzzle.

This Chrome extension offers 480 free puzzles across four difficulty levels — Easy, Medium, Hard, and Insane — each increasing the complexity with longer secret codes, repeated colors, and empty pins. The game also features an engaging multiplayer mode where you can challenge friends or random opponents online to see who can break the code first.

Whether you're a casual player or a code-breaking enthusiast, Real Code Breaker provides hours of brain-training fun completely free. Watch the how-to-play video linked in the game, explore diverse boards, and enjoy a timeless puzzle experience designed for all skill levels.
