About Hidden Object Mystery・Echoes
Three Echoes is a hand-painted point-and-click mystery: a quiet escape-room adventure with hidden-object scenes, locked boxes and a case board full of red string.
Some houses forget. This one remembers.
Nora has come back to her late grandmother's house to empty it and sell it. Behind the dust sheets and the stopped clock, the house is still keeping a secret from one April afternoon in 1958, and someone has been waiting for her all this time.
Then open the second case. A night-shift archivist receives an unmarked parcel: the belongings of a girl who "ran away" in 1987, and a note that says "They closed it too soon." Pin the evidence, connect the clues, and find out who closed the file, and why.
TWO STORIES, ONE ARCHIVE
• The House That Remembers: a bittersweet ghost story told through rooms, letters and memories.
• Cold File: a cold-case investigation through police reports, tapes, photographs and a corkboard of red string.
• 10 chapters each, with two endings in the first story.
WHAT YOU'LL DO
• Search lamp-lit hidden-object scenes. Find everything for three stars, then replay your favourite rooms with the objects in new places.
• Open code locks, dial locks and puzzle boxes. Combine items and use them where they belong.
• Solve hand-made puzzles: sliding blocks, jigsaws, ciphers, radio tuning, grave rubbings, tap codes and more, each built into the story.
• Connect evidence with red string to make deductions and open the next lead.
• Touch the right object and the past flickers back into the room.
MADE TO BE CALM
• Ink-and-watercolour art and an original atmospheric score.
• A three-step hint system that nudges before it tells.
• No jump scares. No timers. No forced ads (optional ads for hints only). No account.
FREE TO START
The first three chapters of each story are free. Unlock the rest of a story with one purchase, get every story with the All Stories bundle, or unlock chapter by chapter with coins from the daily reward. Hints can also be unlocked by watching an optional ad. Coin packs are also available. Purchases can be restored on any device signed in to the same Google account.
A third case, The Magpie Lantern, is on the way.
Best played in landscape, with headphones. Works offline; an internet connection is needed for the daily reward, optional ads and purchases.
Some files are closed for a reason. Open them anyway.
