About this game
Can you crack the code?
Cipher delivers a brand-new cryptography puzzle every day. Each challenge tests a different technique — Caesar shifts, binary, hexadecimal, XOR, Vigenère, Morse, and more. Solve it, track your streak, and come back tomorrow.
🔐 DAILY PUZZLES
A fresh cipher drops every day. You get 5 attempts and 3 hints. An interactive onboarding walks you through how everything works before your first real challenge.
📦 PUZZLE PACKS
Themed collections beyond the daily game — from beginner-friendly sets to spy thrillers, history, space, and fiendish expert chains. Several packs are free; premium packs add story-driven cases and special layouts.
📁 THE ARCHIVE
Miss a day? The archive holds every past puzzle, organized by category. Free users get the last 7 days. Go Pro for the full history.
📚 LEARN
A built-in library of cipher lessons — how each one works, a worked example, and a hands-on "try it yourself" widget. Go from beginner to codebreaker.
📊 TRACK YOUR PROGRESS
See your solve rate, current streak, best times, and average attempts. Pro unlocks advanced breakdowns — performance by difficulty and category, perfect solves, no-hint completions, total play time, and a full-year activity heatmap.
⚡ CIPHER TYPES
• Caesar & ROT — classic letter shifting
• Binary, Decimal & Hex — decode ASCII codes
• Vigenère & Autokey — keyword ciphers
• Morse, Atbash, Affine, rail fence, and many more
🏆 GO PRO
Upgrade to unlock the full archive, unlimited hints, advanced stats, an ad-free experience, and the two-way Toolbox — encode and decode any supported cipher instantly. Available as monthly, yearly, or lifetime. Prefer à la carte? Hint packs and ad removal are also available separately.
🎯 ACHIEVEMENTS
Earn Google Play Games achievements for first solves, long streaks, flawless runs, solving without hints, and major milestones. View your progress board any time from Settings.
🔥 STREAKS
Build a daily solving streak — and streak freezes help protect your run if life gets in the way.
🎨 THEMES
Pick from Hacker (matrix green on black), Dark, Light, or follow your system setting. Status bars adapt automatically.
No account needed. No internet required to play. Just open and solve.
