MARBLEWORKS

A wooden construction set on a birch pegboard. Drag chutes, rails, bumpers, tuned chimes, paddle wheels and seesaws out of the drawer, screw them down, then pull the lever and watch a glass marble find its way to the bell. Fifteen builds and an unlimited workshop; every build in the book has a printed machine that provably works, so nothing here is a puzzle without an answer. Real gravity, real bounce, real rolling contact — the plank you see is the plank the marble hits.

Montgolfier Post

France, 1785. Carry the royal post by hot-air balloon over a hand-tinted copperplate countryside. The wind blows differently at every height: burn to rise into a layer that carries you toward the vermilion meadow, vent to sink onto it, drop ballast for a last step upward, and hand the sealed letter down. Twenty authored routes across five post roads, thermals, downdrafts, the mistral, narrow alpine rings, stamps and a postal-accuracy leaderboard.

Shear-Line Locksmith Bench

Operate a monumental museum cutaway through twelve commissions, diagnose exact pin-stack blockers, and turn only when five fictional joints share one boundary.

Hailstone Descent Funicular

Operate ten tactile alpine mechanisms to explore exact Collatz routes and separate finite observation, exhaustive computation, theorem and open conjecture.

Inkpot

You are an octopus with one night to escape a public aquarium. Drag eight arms independently, haul your boneless body after them, and pour yourself through any gap wider than your beak — the gap is simulated, not scripted, so "will I fit?" is a physical fact, not a locked door. Six continuous areas run from the tank through the filter sump, a bone-dry corridor, the touch pool and the lobby to the outflow. A guard and a rail robot are beaten by watching, and by holding still until your skin matches the tiles. Eight keepsakes, alternate routes, and a replay of every gap you poured through.

Drystone

On a northern English fell the walls are down, and there is no mortar coming. Drystone is a physics game about fitting irregular hand-inked stones: no grid, no snapping, no two alike — only weight, friction and the judgement in your fingers. Break every joint one over two, pour hearting into the core, tie the faces with through-stones, set the copes. Then let go. The years run: gales lean on exposed stone, frost prises at every lazy joint, the ground settles under a hollow core, and Herdwick ewes shoulder her to see if she gives. Eleven commissions. Longevity is the only score.

SHIBORI

The Japanese art of indigo resist-dyeing, made playable. Fold the cloth, clamp the resist over each region, then plunge the whole cloth through the ai vat — deeper with every dip. Clamp on time and a region keeps its shade; miss the moment and the indigo drinks it darker. The fold IS the symmetry, so one clamp blooms a kaleidoscopic pattern across the opened cloth. A real fold-symmetry engine drives it — clamp-then-dip is both demo and regression test. Twelve cloths across three traditions — itajime, kumo, arashi — with a rin-bell score, a cloth gallery, and a free dye studio.

CLAYWRIGHT

The craft of the potter's wheel, in real 3D. Centre the clay, pull the wall up, and shape a spinning vessel to match the ghost of a master form — then fire it and watch the glaze bloom from the kiln. Built on a deterministic throwing engine (every pull and push a pure function of the clay), so the title screen throws its own masterpieces and the demo is the regression test. Twelve vessels across three studios — the everyday table, the celadon studio, and the moon kiln — with crackle, celadon and oxblood glazes, a kiln shelf, and a koto score. Portrait-first, pure JavaScript, no build.

Prisma Cascade

A Peggle-lineage light-through-crystal cascade: drag to aim a comet of light, bounce it through a cavern of faceted prisms where every hit refracts a beam, chimes the backing chord, and bursts chromatic shards across 40 authored levels and 4 mechanics-driven chambers.
