Sound Shadow

THE MAZE IS PITCH BLACK. YOUR SONAR IS THE ONLY LIGHT. Sound Shadow is a stealth heist played in total darkness. Tap to take a silent step. Double-tap to sprint — fast, bright, and loud enough that every guard in earshot turns your way. Each ping paints the maze in neon for a heartbeat: walls, lasers, hidden powerups, and the golden vault you came for. But light is information for you — and sound is information for them. FIVE WAYS TO GET CAUGHT • Patrols walk their routes with sweeping vision cones • Sentries scan chokepoints like searchlights • Hunters are fast, sharp-eyed, and relentless • Listeners barely see, but hear a sprint across the map • Wardens deny whole corridors with their bulk Get glimpsed and suspicion rises — break line of sight before it fills, or the run ends. 75 SECTORS, THREE TIERS 25 Beginner sectors teach you to move like a whisper. 25 Pro sectors sharpen every guard. 25 Elite sectors are honest but merciless — beatable only with the perfect line. FIND THE HIDDEN POWERUPS Freeze the room. Slow every guard. Neutralize one threat. Cloak yourself — unseen but still heard. Or reveal the whole map in one silent flash. FEEL THE DARK True spatial audio puts every footstep around you — play with headphones and hear a patrol pass behind your back. Haptics tick with distant steps and thump when danger is close. • One-thumb controls: tap and double-tap, nothing else • Replay any sector you've beaten; jump tiers anytime • Every breach scored by time and pings • No ads. No accounts. No internet required. Just you and the dark. The vault is waiting. How quiet can you be?

Verdict
The clearest difference is ads: Sound Shadow at none against Challenge Sort's shown. Challenge Sort's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
