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.

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
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).
One Line Numbers
A mobile-first one-stroke number puzzle: start from the colored tile, navigate hollow grids, and connect every numbered block without crossing your path.

KUMIKO — The Lattice Joiner
A fine-art kumiko woodworking puzzle. Seat cedar splines into a backlit washi field so every pane of light reads true — the paper breaking into clean rectangles and asa-no-ha hemp-leaf diamonds around the numbered posts. Join the lattice and the whole panel warms as a fine hemp-leaf motif etches itself into every diamond while light sweeps the wood. Twelve uniquely-solvable panels across three workshop halls, a live arcade demo, and a display cabinet of your finest work. A serene Shakashaka deduction game. Portrait-first, pure JavaScript, no build.

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.

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.
Lantern Field
Minesweeper reborn as a night-festival meadow: light paper lanterns, read the glowing embers, and ribbon-flag the fireflies across three board sizes — first tap always safe, with best-time chasing on a global leaderboard.

Grail Cartographer
A logic puzzle painted as an illuminated map: ink the land of the Grail quest from the knights' conflicting testimony, seal the chapel, and watch a knight walk the map you drew. Twelve authored quests, a daily seed, a gallery of illuminated plates.

SAMPLER
The quiet craft of counted cross-stitch, made playable. Read the counted-thread numbers on each row and column — each an unbroken run of one floss colour, in order — pick a thread, and lay glossy X-stitches into the Aida cloth until the picture appears; then mount it in the hoop. A colour logic puzzle on a real solver that proves every chart has one honest answer, so the title screen stitches its own masterworks and the demo is the regression test. Twelve motifs over three chapters — garden, folk, night — with a music-box score and chalk marks. Portrait-first, pure JavaScript, no build.
