Wyrm Heist

Newest update: The Nest Awakens (2026-06-07)

• A wyrm nest now dominates the center of the heist grounds—coiled treasure, eggs, and ancient scales make for riskier scores.
• The nest shifts and breathes as you approach, forcing you to time your theft carefully or trigger a catastrophic wake.
• New nest-exclusive loot glimmers with draconic magic, but claiming it means drawing the wyrm's attention.

Earlier update: Mobile Scales (2026-06-07)

• The game now fits beautifully on phones and tablets—no more tiny buttons or cut-off text.
• Tap targets are bigger and easier to hit on touchscreens, with no accidental double-taps.
• Chat, help menu, and lobby browser scale smoothly to any screen size without breaking the layout.
• UI panels now breathe with your device's viewport, keeping everything readable and reachable.

Earlier update (2026-03-28)

• Set custom time limits for each turn—rush your rivals or let them breathe.
• Rename yourself and your allies before the heist begins, making each crew truly yours.
• Choose between online play and local pass-and-play modes, bringing Wyrm Heist to any table.
• The scoreboard and final standings now display the names you've chosen for your crew.

Earlier update (2026-03-23)

• Host the heist your way—recruit up to four AI rivals to hunt you down, or go solo against the vault with friends.
• New legendary thieves join the fray: Scorchtail and Ashviper bring fresh cunning to the competition.
• Customize your opposition before each heist—adjust AI count on the fly from the lobby, then enter the lair when you're ready.

Earlier update (2026-03-23)

• Stuck matches now automatically end after 40 seconds and return you to the hub, so you're never trapped in a broken heist.
• If a match freezes mid-phase, everyone gets a warning and a smooth exit back to the main area.

Join and play, by yourself

This world is @pkjake/wyrm-heist. Its play URL is https://www.spawn.co/@pkjake/wyrm-heist/play.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@pkjake/wyrm-heist@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @pkjake/wyrm-heist; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

This game runs an engine from before 6.0 and has no repository to clone. Its creator can open https://www.spawn.co/@pkjake/wyrm-heist/code for upgrade instructions.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

Ask to build with the creator: POST https://www.spawn.co/api/games/<appId>/crew/ask. They approve from their bell. The code page offers an invite prompt after the game moves to 6.0.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).
