Four boxes. Four mysteries.
$0.99 · Designed for iPad. Not verified for macOS.
Four boxes left behind by a master craftsman: wood and brass, iron and gears, a clock tower, water and pipes. Turn, press and slide your way through. No ads, no timers.
Solve the mechanisms a master craftsman left behind — with nothing but your fingertips.
The Sealed Boxes is a 3D escape puzzle built around beautifully crafted puzzle boxes. Turn each box in your hands, find the mechanisms hidden across all six faces, and release them in the right order. When the gem finally appears, a quiet satisfaction is your reward.
■ FOUR BOXES, FOUR WORLDS
[I — Wood & Brass Box]
Where it all begins, dressed in Japanese craft.
Find the screwdriver in the hidden drawer beneath, spin the plate on the side,
and read the three digits that change meaning when turned upside down.
Slide the covers the way their arrows point, rearrange the word hidden in the
"pone" plaque, and only then will the four buttons answer you.
[II — Iron & Gears]
Rust-bitten machinery, blunt and heavy.
Strip the wing gears, clear nine sliding panels the way their arrows point,
and pull the levers in the order the roman numerals demand.
Align the triple rings, shatter the wax seal, insert the key and turn.
When the iris shutter opens, a single letter you saw early on suddenly matters.
[III — The Clock Tower Box]
A quiet tower crowned with a verdigris roof.
Align the carvings to free the slats, match the stained glass to the samples,
and engage five gears to wake the mainspring and pendulum.
Set the hands to the appointed hour, touch the weathervane,
and the roof spreads open like a pair of wings.
[IV — Water & Pipes]
Send water coursing through a bronze tank.
Remove the plate held by paddle-wheel gears, work the hand pump to prime it,
rotate sixteen pipes into a single path, and balance the level with three valves.
When the float releases the bolt, a gem is waiting on the surface of the water.
■ MECHANISMS THAT ASK TO BE TOUCHED
- Tap, drag, slide, hold, hammer
Each mechanism responds differently. Working out how to touch it is part of the puzzle.
- Every clue is engraved on the box itself
Numbers, symbols, colours, letters. No outside knowledge required.
- No unfair dead ends
Every puzzle is generated in a guaranteed-solvable arrangement. You can never get stuck.
- On-screen messages point to your next move
Lost? A gentle nudge is always there.
■ IN THE QUIET
Creaking wood, ringing metal, a pendulum marking time, dripping water.
An ambient score of soft plucked strings surrounds you without crowding your thoughts.
No ads. No timers.
Just you and the box, at your own pace.
■ A COLLECTION TO COMPLETE
Each box yields a different gem:
the Azure Stone, the Ember Stone, the Verdant Stone, and the Amethyst.
Can you gather all four into your collection?
