Ultimate Code Breaker

One machine. Seventeen ways to break the code—and a Designer for challenges built around your own rules. Ultimate Code Breaker brings classic number and colour deduction games together in one tactile cipher-machine collection.

A featured premium variation is available for one complete free round each day. Upgrade to Ultimate once to permanently unlock every curated game, including future curated variations. BUILD YOUR OWN WITH ULTIMATE DESIGNER Choose numbers or colours, code length, available symbols, repeats, attempts, feedback style, memory rules and time pressure. Save and duplicate designs, then track statistics separately for every rules revision. Custom games stay local and do not enter public leaderboards because custom difficulties are not directly comparable. MEASURE YOUR MASTERY Track games played, codes broken, success rate, total and average solving time, best time and win streaks overall, by category and by game. Supported curated modes can also use platform leaderboards. ACCESSIBLE AND OFFLINE-FRIENDLY Symbols accompany colour, clues are described for screen readers, and the app follows system text, dark theme and reduced-motion settings. Core play, saved designs and local statistics do not require a Technova account. Ultimate and Ultimate Designer are optional one-time, non-subscription purchases. Purchases and restoration are handled by Google Play. Apple and Google purchases are separate. Saved games and statistics are stored locally on your device.
