Our new mobile interactive and gamified approach makes it easy and fun to learn Linux usage from the basic, the app gives practical day to day knowledge and cool tips in a gameful way.

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 - Hints when you're stuck, flags when you win - Slick neon terminal design with satisfying animations 13 skill paths. 211 levels. Easy to expert. FREE TO START Play the first 10 levels free. Unlock all 211 levels and every interactive lab with a single one-time purchase — no subscription, ever. 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.
