Shadow theatre · one rule
Move the light, not the soul.
Lampion is a quiet shadow-theatre puzzle. The soul walks only where your light doesn't reach. Tap a station and the lantern flies there, redrawing every shadow on the board — and the soul walks as far as the new darkness allows.

The rule
Shadow is solid ground.
In the open dark there's no path at all, and in bare light there's no cover. Your lantern has to make both at once — and keep making them while the soul moves.
-
Tap a station
The lantern flies there, and every shadow on the board changes.
-
Walk the dark
The soul moves as far as the new shadow allows.
-
Think freely
No timer, unlimited undo — and the game tells you when a position can't be solved.
Worlds
From a stone garden to a tower.
Sixty scenes across ten chapters — a ruined wall, a lake, a pier, an ice field, a street of lanterns, a cellar, a mill yard, a hall of mirrors.
-
A puzzle every night
Solve it and your lantern garland grows. Miss one and nothing is taken away.
-
A perfect run, always
Every scene has a machine-verified best solution.
