Try it with your eyes: cross them until the circle under “Illenium” in the first two images comes together in the centre, then look straight at them again. Crossed and uncrossed, back and forth — that is how much 3D is really in there. Stereogramming lets your mind know how to see it.

Laid out by hand today โ€” but a sheet like this is really a law: size from the rank, place from the address, and the eye does the rest. One day sitoolz will hand that to anyone, so the shimmer and depth you can feel in a grid like this is something you compose rather than something you draw.

A PLAYGROUND BY LARS ROCHA

Range Arcade

Fifty-eight arcade worlds, two familiar editions, and eight adventures. Visit Apartment 3B, untangle a laser route, or welcome an airship above Venus. Your playground keeps growing, one small story at a time.

โ—† NEW ENGINE โ—†

Try Wander as a Rust engine.

The same land laws, rewritten in Rust and compiled to WebGPU โ€” a pod race on nine ranges, three of which draw a closed circuit of their own and six of which lay sixteen gates from the world’s own name. Nothing is stored: no heightmap, no seed table, no track file. The laws are checked against this site’s own JavaScript, bit for bit.

โ˜… NEW IN THE LAST DAY โ˜…

Seventeen new places, and two new games.

Silo Line, a tower game where five waves walk a winding road to your keep and you build silos and turrets to stop them. Hull Down, where the crest is worth more than the gun. Three tanks, eleven hover-jets, a ceiling of 1,260 metres, and ten ranges written by the law. One page, every link, nothing to set up.

Open them all โ†—

โ—ณ THE LAW TOOLS โ—ณ

See the law. Check the way through.

The geometry inspector: rooms built from the law and every route through them proved walkable before it is drawn, a moving window, persistent edits, laws composed together, time and lights, parameter sweeps, ruler patterns, XOR lamps, a sieve observatory, modular blueprints, evidence cards, and the measurements behind all of it. Thirty laboratories. Beside it, the law workbench, where every decision the law makes is on one page with the reason for each one.

Why is that hill there?

Ask most generated worlds that and there is no answer: they are made of noise, which repeats reliably and explains nothing. These are made of a law. Five numbers you can check on paper, then the same five decisions as a landscape, as rooms with every route through them proved walkable, and finally as somewhere to stand. Five minutes, from the beginning.

Start with five numbers โ†—

โ—ˆ NEW โ—ˆ

Where both mirrors cut.

Two mirrors fold the same addresses โ€” one on a lattice of powers of two, one on the squares. Out of true they agree almost nowhere, and the rare places where both still cut are the seams. A seamโ€™s position is settled by arithmetic alone: no table, no seed, no spawn rate, and the same seam in the same place for everyone. Three ranges to walk, three survey craft, and two games you can play on the page itself โ€” one of them has a right answer that needs no simulation at all.

Three ranges, three craft, two games โ†—

โ˜… PREMIERE โ˜…

A law you can read, seven ranges it writes, and Pod Racing

The Indexin selection law now writes whole landscapes: pick a stride, a stripe, a sieve and a mask, count how many of the last few square addresses the law keeps, and that count is the tier the ground stands on. No noise anywhere, and the Rule panel will tell you why any hill is the height it is. Ten ranges now, one law, and a lit doorway into twenty-five courtyards compiled from the village you are standing in. Three of them are built for the air: the Thousand Steps climbs in cliffs a hundred and eighty blocks high, the Deep Vane cuts gorges through five hundred blocks of rock, and the Ember Steps carries the rift's lava along its floors. Walk them, take a hoverboard over them, pod-race the Step Circuit, rally the Ember Run through the lava, or fly the lot: eight new hover-jets, and the ceiling is twelve hundred and sixty metres. The law workbench opens the same decisions on a page, and the Dropped Two is the Terraces with one remainder thrown away instead of another, which rewrites the whole skyline and nothing else. Also still new: seven pods, three laps, a slot canyon, the Needles and a jump over the gorge, with a big race HUD and lit gates. Type any word and it lays a new circuit. And three new tanks, led by the Longbow, whose shell carries about a hundred and seventy blocks where the Bastion's carries seventy-four, with four grounds built to take them to, and two new games: Silo Line, where five waves come up a winding road and you build silos and turrets to stop them, and Hull Down, where the crest is worth more than the gun.

WANDER ยท SIXTY-SEVEN WORLDS TO WALK, FLY, BUILD, SAIL, DRIVE, RACE AND RUMBLE

Wander

Stand inside the RangeBlends worlds. Walk, fly, float, dig and build through eighty-two of them, on a phone or on a big screen, with the horizon thousands of cells away. New: the Proving Ground, a tank duel against a forest that shows its thinking; Six Hills, six guns on the high ground and shells lobbed over the crests; the Speedway, three laps in a blocky car of your choosing; and the Rumble Road and the Crossing, armed racing with oil, mines, rockets, shields and a workshop, the way the old cabinets had it; and now a Grand Prix, a Demolition Derby, the Gauntlet's endless tank waves, Capture the Hills with wingmen, a Hill Climb Rally with real air, the Convoy Run, the Midnight Circuit under street lamps, the Stunt Park and the Fortress Assault, all on a new graphics library: real shadows, headlights that light the road, sparks, debris and fire. Any world can now be crossed by hovercraft or buggy (the Hover button, or G), walkers carry a lantern at night, and there are four new worlds to wander (the Roof of the World, the Mesa Lands, the Reef Sea, the Patchwork Range) and four more games: the Hover Sprint, the Lantern Run, Car Ball and the Meteor Run. Then the air: a plane for every world, ring races over the Archipelago and the Roof of the World, and a dogfight over the Reef Sea; weather you can choose in every garage (rain that costs grip, storms with lightning, fog); and worlds that are lived in, with other travellers on the ground, the water and in the sky, and villages that glow at night.

  • Your own valley, the ruler valley, the living bank, the settlements road, a river basin, the gallery's named valleys, the highlands of valleys side by side, the range drawn three ways, the sequence wall of rule 30 itself, the build plot, the confluence: from a spring to the sea in one walk. Then the epic worlds: the Great Range, a summit 2,200 blocks tall where g + 1 is 2^24; the Dunes, the same law at a whisper; the Long Range with its settled vale; the Builders' Range; and the Archipelago with its volcano.
  • Free exploration, or a lantern hunt: six lanterns, six true things about the world you are in.
  • The hour turns, the almanac's weather arrives on its exact clock, every spot has a share link and a postcard, and what you build fits in a string.
  • Named villages, bridges and peaks; races whose runs friends can try to beat; hunt sets across worlds and a daily lantern; an album book printed as a PDF in the browser.

WANDER ยท SHOWCASE

See what you're about to get into.

It plays by itself; tap any picture to see it big, or pick a gallery below.

NEW ยท A PUZZLE MADE OF EVEN AND ODD

The Square Lanterns

Every lantern carries a number and burns a flame for each prime it holds an odd number of times. Light the ones that put each other out, and their product is a perfect square.

  • Six streets, from four lanterns to thirteen, with a hint that is never wrong.
  • Watch it solved: the same row as a matrix, stripped and pivoted step by step.
  • The Great Square: a town of 1,500 lanterns, thinned by elimination and finished by block Lanczos, thirty-two answers at a time.
Light the lanterns โ†—

NEW ยท JUST PLAY

Arcade Fun

  • A wrong move becomes the right one, with a friendly note that says why.

RANGE ARCADE ยท CASUAL EDITION

Casual edition

The same fifty-eight worlds, rules and trained models, with a presentation aimed at short drop-in sessions.

  • Tips are in plain words, with a Show-the-math button that restores the original sentence.
  • Welcome cards open with an everyday metaphor; the manuals keep the full mathematics.
  • Model-guided worlds show a move counter and worded choice labels; numeric values appear when the brain view is open.
  • Every ending stamps a passport and offers the next unfinished world; the landing page adds a stamp grid, a visit streak and a daily trio.
  • Night-frame games add an encore button and a shared daily seed. Milestone Post keeps its address hint through medium shifts.
