About

CipherWalk turns cities into an outdoor escape room. You and your team walk to real places around the city, and at each one there's a puzzle waiting. The puzzles are built for collaboration: each teammate sees a different clue, and you only crack them by piecing together what each of you can see. Solve a puzzle and the next location unlocks. The app is best from the age of 13+, because the puzzles are difficult and built for adults. Free to start. Additional quests are unlocked via in-app purchase, one purchase per team of 2 to 4 players. WHAT'S DIFFERENT • Real multiplayer. Each player has their own view, and every view and the surroundings are required to solve each puzzle. • In the city, not on top of it. We write each puzzle for the specific street it's on. The architecture, the plaques, the bits of the city most people walk past. • One-time payment. No subscription. HOW IT WORKS 1. One player on the team taps Unlock Quest, picks a team size of 2 to 4, and pays once via in-app purchase. The whole team is covered. 2. Meet at the start location. The organizer creates the team, teammates join free with the team code. 3. Walk to each stop, solve the puzzle, beat the clock. WHAT YOU NEED • A charged smartphone per player with an internet connection. The app stays in touch with our servers for the whole quest. • A team of 2 to 4 players. Only one player needs to buy the unlock. • Comfortable walking shoes. WHEN TO PLAY Daylight works best, you'll be reading clues off walls, plaques, and signs. Light rain or cold doesn't matter; just dress for it. WHERE Zurich today. More cities later. Browse the available quests in the app or on our website. PRIVACY No tracking, no data sales, no ads. The app uses your location only while a quest is open, and only to know when you've reached the next stop. The account is anonymous. Bring your team. Decrypt the city.
