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.

HELIOGRAPH — Signals Across the Iron Valleys
The line went dead at Cold Hollow and you are the new signal-keeper. Turn brass mirrors to walk a beam of sunlight across a hand-drawn valley and into the receiving station — then learn to split white light through a prism into three colours for three valleys, to husband a beam through fog that drains it, and to arrive on the beat while army shutters open and close. Twenty-four stations across five chapters, every one machine-proved solvable, with an honest par and a quiet score of plucked strings and glass bells.

Observatory Grid Logic
A standalone portrait-first constraint deduction puzzle. Use written clues to assign each telescope station a unique star target and signal band, then submit the exact chart.
Ice Slide Logic Remix
An ice-slide puzzle. Pick a direction and the skater **glides until a wall (or the exit portal) stops them** — there's no stopping mid-glide, so the logic is in planning which walls to carom off. Sweep over every gem, then come to rest on the exit to clear the level.
Light Grid Logic Remix
A **Lights Out** puzzle. Tap a bulb to **toggle it and its four orthogonal neighbours**; turn the whole grid off to clear the board. Order doesn't matter — *parity* does, so it's about *which* cells you press, not when. Undo and reset any time, and chase **par** (the number of presses the level was built from).
Relay Circuit Logic Remix
A standalone portrait-first relay-circuit logic puzzle.

A beautiful Star Battle logic puzzle set against a night sky. Place one star in every row, column, and coloured region — and no two stars may touch, not even diagonally. Every sky is uniquely solvable by pure deduction. Vector art, synth audio, standalone.

SEKITEI
A fine-art karesansui puzzle. Rake the white gravel around moss islets and carved stones until every garden reads true — each islet the size of its stone, the gravel one connected sea that never pools into a solid square. Solve it and the flat sand reorganises into concentric raking currents flowing around every islet while the moss blooms. Twelve uniquely-solvable gardens across three seasons, a live arcade demo, and a Garden Book of all you light. A serene Nurikabe deduction game. Portrait-first, pure JavaScript, no build.

Interlock — A Signal Box, 1910
You are the signalman. An illuminated enamel diagram shows the road above; below stands a brass frame of fourteen painted levers, tied together underneath by iron — and that iron is the puzzle. A signal will not come off until the points beneath it lie right and their lock is bolted. Pull a lever the interlocking forbids and it thunks dead in your hand and names the lever in the way. Beyond the box there is only the block bell: 4 for an express, 3-1 for a passenger, 2 when a train enters the section. Twelve turns of duty, graded on punctuality, safety and protocol.
