Answer with your camera. Every day Kaptr deals one sealed case: a photo riddle about something in the world around you. It's a riddle game and a scavenger hunt in one: rip the pack, work out what it means, then go find the real thing and photograph it. The photo is your only guess. The Examiner scores it out of 100, and the clock is running from the moment you open the case. EVERY PHOTO IS A PULL Your score lands as a card: Bronze, Silver, Gold, or Prismatic for 90 and up. Fewer hints and a faster find mean a better pull. Miss it and the day still closes cleanly, ready for tomorrow's case. TODAY One case a day, the same for everyone. Build a run day by day, watch your week fill with cards, and see where you land on today's board. PLAY Play the world or your friends. Global Tic Tac Toe pairs you with another player, and every move is a photo against a 60-second clock. Start private games with friends, or take on a Themed Hunt: twelve rounds across four levels that get more demanding. BINDER Collect the world around you. Catch real things on camera, from butterflies to street food, and fill collections like Naturalist, Epicurean, Urban, and Globetrotter. ACHIEVEMENTS Sixteen achievements in Game Center, from your first case to a hundred-day run. SHARE THE CARD Every result becomes a card you can share, with your photo blurred or left off so you never spoil the answer for a friend. YOUR PHOTOS, YOUR CALL Every shot is judged in memory and the judged copy is dropped. By default Kaptr also keeps your Kwest and Themed Hunt photos for your eyes only, and photos from private games with friends, visible to friends in that game who have Kaptr Plus and deleted 30 days after the game. Public games keep nothing. One switch in Settings turns uploads off. PLAY BEFORE YOU SIGN UP Your first case is free, no account needed. Sign in with Google or Apple when you want to keep your run. KAPTR PLUS Optional. See your friends' photos on the board in private games, more daily tries, unlimited friend and Global games, more catches a day, every hunt level, and four extra card styles: Darkroom, Instant, Signal, and Sticker. Everything else is free. One riddle a day. Answer it with your camera. Kaptr Plus is a monthly auto-renewing subscription. Payment is charged to your Apple Account and renews each month unless cancelled at least 24 hours before the period ends. Manage or cancel in your Apple Account settings.
