Safe Cracker

Read full description

Your Apple Watch already had the one thing this game needed: a Digital Crown that turns like a real dial. Safe Cracker throws away the touchscreen. No taps, no swipes — you crack every combination by turning the Crown, exactly the way a real safecracker feels for the tumblers: pick a direction, count your passes, ease onto the number, and hold. DESIGNED FOR THE CROWN, NOT PORTED TO IT Every one of the 30 levels was built and playtested entirely through Crown rotation. Haptics click under your finger on every number you pass. The dial has real inertia and real resistance — this isn't a phone game squeezed onto your wrist. 30 HAND-CRACKED LEVELS Start with 3 free levels, then unlock the full vault with a single $1.99 purchase — no subscriptions, no ads, ever. - Standard combinations that ramp from simple to genuinely tricky - Reversed dials that scramble your sense of direction - Earthquake levels that jolt the dial off target mid-turn - Rusty zones that fight your Crown with extra resistance - Oily dials that keep coasting after you let go - Boss vaults that mix multiple mechanics step by step DEDUCTION MODE The last 10 levels hide the target number entirely. Crack the code by feel and clues alone — pure muscle-memory puzzle solving. HARD MODE For purists: any mistake resets the entire level, just like a real safe. No mercy, no partial credit. MADE TO BE FELT Every pass, every lock-in has its own haptic and sound, tuned so you can play by feel with your watch tucked under a sleeve. COLLECT & COMPETE Unlock 4 dial finishes (Classic Silver, Vintage Gold, Obsidian, Crystal) as you progress, chase 9 achievements, and track your fastest cracks. BUILT FOR EVERYONE Full VoiceOver support and colorblind-friendly indicators, in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, German, and French. Your wrist is the safe. Turn the Crown.
