Open The Silent Atlas. Build visual programs, recover melodies and unite five lost keys. Begin with a free chapter, then discover a fresh daily signal. A sealed book. Five lost keys. An island erased from the map. Open The Silent Atlas and follow a trail of strange machines through a harbour, bell tower, glasshouse, observatory and buried gate. Each discovery helps you solve the next device. Every chapter brings you closer to the treasure. CRACK THE COMPUTER Arrange visual code blocks to reverse symbols, shift their order, swap pairs and remove noise. Watch your program transform two different signals. Find the sequence that makes both match. MAKE THE LOCK SING Listen to a recording and repeat its notes on coloured symbol pads. Apply the rule you recovered, then combine short and long notes to open the musical lock. Replay, slow down or follow the visible note guide with sound off. BRING THE ATLAS TO LIFE Open chests, collect five keys and reveal the island on your discovery map. Each key holds a musical fragment. Bring them together to solve the final constellation and unlock the emerald atlas. A NEW SIGNAL EACH DAY Your first story key opens Daily dispatch: a fresh computer puzzle with permanent relics to collect. Return at your own pace. There is no streak penalty. LEARN BY PLAYING Interactive practice lets you try each device before the adventure. Visual hints demonstrate the moves. Chapter puzzles have no timer or lost lives, and completed keys stay safe when you replay. START FREE Play The Harbour and its three devices for free.
