CLOISON
A fine-art cloisonné enamel puzzle. Drag gold wire (掐丝) between matching enamel gems until every compartment of a gilt bronze plaque is enclosed — then the kiln fires and the vitreous colour sets in a glowing wash of scrollwork. A connect-the-flow puzzle refined into Chinese metalwork: twelve plaques across three chapters (Lotus Court, Phoenix Hall, Dragon Throne), hand-drawn vitreous enamel and gold wire, cabochon gems, a guzheng score, an atelier gallery of fired works, and a deterministic engine whose title screen fires itself. Portrait-first, pure JavaScript, no build.

CINNABAR
A fine-art Chinese papercut (jianzhi) puzzle. Fold a round sheet of vermilion paper, glide the scissors through the pale grounds and every symmetry fold snips at once, so the red silhouette blooms into a radial window-flower over warm lantern light; pierce the locked hearts with the awl for a flawless cut. Twelve window-flowers across three chapters — Spring Festival hearth-gold, Garden jade, and Celestial moon-silver — with a guzheng score, a papercut gallery of your finished work, and a deterministic engine whose title screen cuts itself.

Mudlark
London, 1890s. Twice a day the Thames pulls back and hands you two thousand years of lost property. Walk a hand-painted foreshore at low water, read the ground for a gleam or a dark crusted stain, and work it before the flood returns. Brush too fast and a pipe stem snaps; put iron on a Roman coin and you scar it forever. What you free comes up in the only true colour on a grey shore — name its era under the loupe while the mud is still on it and you earn its provenance, and the human accident that put it in the river. Eight tides, thirty-four researched finds, one cabinet museum.

INTARSIA
A fine-art marquetry puzzle. Drag across the cells to cut each veneer rectangle so its area matches the brass pin it covers and the whole panel tiles without a gap — then pieces resolve into grain-matched wood, the seams take a glue-line, the brass polishes, and a French-polish sheen sweeps the finished panel. Twelve uniquely-solvable panels across three chapters — parquet, boulle brass-and-tortoiseshell inlay, and exotic marquetry — plus a Cabinet of everything you have fitted. The title screen is a live joiner's demo on the real renderer. Portrait-first, pure JavaScript, no build.

Windlass
You are the volunteer keeper of the Twinney flight, a heritage staircase of English canal locks, for one summer. It is painted as a storybook gouache cross-section with genuinely simulated water: every chamber fills by conservation of volume through the paddle gear you crank, and a narrowboat floats only as high as the water you put under her. Twelve days carry you from a single lock to a staircase pair sharing one gate, then to side ponds that recycle half a lockful through a drought. Hang a stern on the cill or drain a pound and you will know it. Water is a budget; the flight is a machine.

Pixel Azure Koi Current Puzzle
A portrait-first pixel current puzzle. Players rotate stream tiles to guide a shrine koi from reed gate to moon gate, collecting pearls while avoiding reef shadows.
SIDEREAL
You keep a brass orrery. A patron names the bodies and the hour; you cannot move the sky, only the gearing that drives each arm. Fit a pair of wheels to every spindle — a bigger driven wheel turns the arm slower — read what the machine predicts, and let it run until they come round to the same bearing.
