MC World Maker

New here? Just hit ▶ Play a world. Everything below is optional — Playing covers the game itself, and Building your own worlds is there for when you want to make one.

🎮 Playing

1. Pick a world and drop in. Hit ▶ Play a world, or choose a world card — Copper Canyon Relay, Frostvault Expedition, Mangrove Moonport, Deepstone Reactor Run, Titanic Abyss Waterworld, and more — and you're straight into full 3D.
2. Move, mine, and place. Left‑click mines, right‑click places (on touch, pick the ⛏ slot to tap‑mine). Hold to keep mining like survival. Choose Break: Multi‑hit (blocks crack over several swings) or Break: 1‑hit in the World panel. Press Craft or C to turn what you mine into useful parts. On phones it opens fullscreen with auto‑hiding controls and a joystick + JUMP button.
3. Use your gear. The slingshot lands sharper marble hits. Hold the grapple to pull yourself in, release to let go, reconnect mid‑air, or perch where the pull ends. Water, lava, redstone, pistons, elevators, note blocks, gold hunt blocks, and explosives all react while you play — and golden blocks glow in the dark and through glass.
4. Start a game. Featured worlds ship with built‑in game modes behind the Games button. Turbo Oval seats you in a named kart at launch and auto-joins seated drivers to a synchronized checkpointed race every five minutes. Watch the lobby countdown, finish three laps, and claim the indestructible voxel Hall of Speed. Press R for a quick kart rescue, exit whenever you want to explore, or ride the cyan spectator lifts to the skyline decks. In Doom Base, demons throw fireballs back at you.
5. Keep an adventure going. Daily runs are quick warm-ups; the weekly expedition asks for a few worlds, gold finds, and finished games. Your local world passport remembers favorites, recent and unplayed worlds, plays, gold, and best scores — no account or public ranking.
6. Play with friends. The Live Server card puts you and your friends in one shared world: everyone sees each other's avatars, mining, building, slingshot hits, and grapple swings in real time.

🧱 Building your own worlds

1. Generate one from a prompt. Type an idea like castle island with rivers, nether arena, or starter village by a lake. The built-in procedural generator is local and free; the status only says AI when your connected model returns renderable voxel shapes. Your optional API key is held only in the open tab's memory and must be re-entered after reload, tab close, or on a new day.
2. Turn a photo into blocks. Open Photo to World, choose a PNG, JPEG, or WebP, then make either a close pixel mural or a walkable 3D relief. It runs entirely in your browser: the image is not uploaded, stored, or sent to an AI service.
3. Or start from the Library — structures, life assets, and pre-generated 3D worlds: oceans, islands, mountains, forests, arcade runs, villages, redstone labs, and more — then sculpt from there.
4. Pick a block from the palette on the left (hover any swatch for its name), then paint on the grid. Tools include adjustable-size Brush and Mine, plus Line, Rectangle, Circle, Fill, and Pick. Hold Shift while dragging a rectangle or circle to fill it. Turn on Mirror for symmetric builds. Resize & zoom any time — your work is kept.
5. Stack layers to build in 3D. Use the Layers bar to Add, Duplicate, and switch layers ([ / ]) — onion skin shows the layer below for alignment. Select an area and choose Extrude up to carry its solid blocks into the next level. The preview updates as you work, and PLAY NOW drops you into your world.
6. Check your materials. The list below the grid counts every block (and stacks) so you know exactly what to gather in‑game.
7. Keep many worlds. The 🗂 Projects manager saves every build separately — never overwriting — with a thumbnail and a dated name. Switch, ★ star, fork, rename, or delete; projects are stored privately in your browser.
8. Share, export, or print: GIF, PNG, a share link, a build guide, a .litematic for Litematica (every layer included), a WorldEdit .schem for your server, a vanilla structure .nbt, or a voxel STL. The print button opens the 3D Printing Instant Quote tool with your STL already loaded.

Tip: in Floors mode each layer is one height level — build floor by floor. Textures are custom generated for this game and do not copy Minecraft files; MC World Maker is not affiliated with Mojang or Microsoft. Keyboard shortcuts can be remapped in Canvas → Keys and are remembered in this browser.
