211 hands-on challenges: solve ciphers, work SQL and XSS labs, map simulated networks, level up.
Real cybersecurity skills in a game.
10 free levels.
Cybersecurity, turned into a puzzle game. CipherQuest breaks real security concepts into 211 bite-sized, hands-on challenges you can play anywhere. No setup, no virtual machines, no risk — just you, a simulated terminal, and a flag to capture.
Inspired by Capture-The-Flag (CTF) competitions, CipherQuest teaches the concepts security professionals use every day, wrapped in a fast, gamified experience.
WHAT YOU'LL LEARN
- Linux & the command line — ls, cat, grep, find, permissions, file systems
- Cryptography — Base64, hex, Caesar, ROT13, Vigenère, Morse, hashing
- Web security — SQL injection, XSS, IDOR, CSRF, SSRF, JWT, and the fixes for each
- Recon & scanning — port and service discovery, banner reading, open-source intelligence
- Digital forensics — log analysis, packet inspection, steganography, file carving
- Memory safety — buffer overflows, ASLR, and why modern defenses exist
- Reverse engineering, networking fundamentals, and connected-device security
INTERACTIVE LABS
This isn't multiple choice. Every lab is a self-contained simulation that runs on your device:
- A SQL injection console with a schema browser — see exactly why unsanitized input breaks a login
- An XSS lab that runs your payload against a fake page so you can watch the flaw happen
- An animated port and service scanner
- A network map you explore host by host
- A password-hash lab that shows why weak passwords fall in seconds
- An encoder/decoder tool bench and a fully simulated Linux terminal
BUILT TO KEEP YOU LEARNING
- Earn XP and level up as you go
- Unlock badges and keep daily streaks
- Step-by-step tutorials on every challenge — start as a complete beginner

100% SIMULATED, 100% OFFLINE
CipherQuest never connects to, scans, or interacts with any real system. Every "server", "database" and "network" in the app is fictional data generated on your device. The app provides no tools that work against real systems and no content about circumventing the security of any device, platform or operating system.
Whether you're studying for a security certification, prepping for CTF competitions, or just curious how digital security actually works, CipherQuest is the most enjoyable way to build the fundamentals.
