Neon Circuit Weave

Connect matching neon signals without crossing a cable across a 50-sector arcade puzzle campaign.

Screw Agent Squad

A portrait-first tactile logic puzzle where players unscrew layered machines, choose the right driver bits, read hidden structure, and extract every part in the correct order across 36 missions.

TIMBERPAW

Lay painted planks across a river so Bodi the beaver bridgewright can walk home. 120 spans across eight stretches of water, each one carved and then proven solvable by an exact-cover solver before it ships. Tap to turn a plank, find the brass hinge on the folded ones, and let Foresight warn you the moment your own moves make a road impossible to close. Remixed from Capybara Causeway Academy: the drag-to-fit bridge puzzle is inherited, while the levels, art, character and every system are new.

Mirror Wake

Rotate mirrors to split a sunbeam across every sleeping beacon.

Capybara Goes to School

A cozy portrait-first polyomino bridge puzzle. Lay painted planks across a river so Bodi can reach the schoolhouse on the far bank — 120 spans across eight stretches of water, every one provably solvable by an exact-cover solver. Tap to turn planks, find the brass hinge on folded ones, and let Foresight warn you the moment your own moves make the road impossible to close.

AINA

A fine-art light puzzle in a mirror palace at night. Tap to set silvered mirror tesserae on the diagonal and bend a warm candle's beam through the hall until every glass lamp is lit. Twelve chambers across three chapters — the Antechamber, the Court of Mirrors, and the Dome of Light — introduce amber, rose and jade beams, fixed mirrors and carved columns, up to a six-lamp finale. A deterministic beam tracer makes the title screen a live āina-kāri demo on the real renderer, and a Hall of Mirrors remembers every chamber you light. Portrait-first, pure JavaScript, no build.

KAKEHASHI

A serene fine-art Bridges (Hashiwokakero) puzzle in a night water-garden. Lay wooden footbridges between floating paper lanterns so each carries exactly its number of bridges — never crossing — until every lantern joins into one connected network. Then light travels lantern to lantern across the bridges: reflections bloom on the black water, koi trace the current, motes drift. Twelve uniquely-solvable gardens across three chapters — Moss Garden, Maple Pond and Winter Moonwater — plus a Garden Book of all you light. The title screen is a live demo. Portrait-first, pure JavaScript, no build.

SHUNT

A rail yard shunting puzzle in 3D. A siding is a stack, the lead is short, and the dispatch sheet wants the wagons in an order the yard refuses to hand you. Six sheets, three yards, one saddle-tank shunter — and a move budget that makes you plan before you touch the throttle.

Seed Cipher

Deduce six escalating bio-vault protocols with longer codes, duplicate runes, scans, and positional clues.

Dormouse Detail Bureau Remix

An offline-ready portrait tactile puzzle remixed from **Screw Agent Squad** (`dES-XfSlV48NYKWc`). The complete 36-case layered-mechanism campaign remains intact, now starring **Mica**, a precision dormouse technician with cyan inspection loupes and interchangeable driver gauntlets.

Clockwright

Mesh brass gears from spring to hands so each clock face keeps honest time.

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.

Arrow Escape

Untangle glowing arrow-snakes. Tap a snake to slither it off the board — but only if its head's path is clear. Snakes block each other, so clear them in the right order to reveal the picture. A relaxing one-finger logic puzzle.

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.

Create a mobile puzzle game called: "Brain Mast (Remix)

Brain Master Africa - a premium puzzle and brain-training game with 100 levels across Logic, Memory, Numbers, Words, and Quiz modes. Features daily challenges, streak rewards, achievements, leaderboard, and Brainy the AI guide. Black & gold African-inspired design.

Observatory Grid Logic Remix

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.

Mosaic Logic Weaver Remix

A mobile-first Three.js arcade logic game. Rotate four glyph columns so incoming proof tiles land on matching mosaic cells before the focus meter breaks.

Tea Code

Resolve silent tea patterns through steeping weight, aroma families, pairings, reflection, and measured tastings.

Alchemist Glass

Deduce stained-glass elixirs through heat, pigment families, hidden bonds, mirrors, and limited refraction scans.

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.

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.
