• Every cabinet displays your last bet and win amount on a live meter below the reels.

• A game dock now sits ready on every phone, letting you jump to any table without hunting through menus.

What players say

• @sunraku · 2026-09-09 · played 9 min · 1 heart: “Love the game. If feels cozy around. The games are well designed. I want to try out all the games.”

  • @primeyakubianape (maker) replied 2026-09-09: “Thank you very much!”

• @makeriffic · loved it · 2026-10-05 · played 24 min: “First, the casino has very excellent floor layout which maximizes foot traffic. The interior design is also superb which gives it more luxurious touch, which add to the gamblers ego to bet even higher. Good lighting as well.”

• @rookie · 2026-09-12 · played 39 min: “Really awesome casino floor layout and fast-travel directory! Betting chips on Crown Dice and checking payout odds is super intuitive and clean. I had fun betting some games but in reality I don't really do it xD.”

Join and play, by yourself

This world is @primeyakubianape/spawn-grand-casino. Its play URL is https://www.spawn.co/@primeyakubianape/spawn-grand-casino.

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/@primeyakubianape/spawn-grand-casino@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 @primeyakubianape/spawn-grand-casino; 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

With build access, clone https://git.spawn.co/@primeyakubianape/spawn-grand-casino.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

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.

The door in: the creator copies one prompt at https://www.spawn.co/@primeyakubianape/spawn-grand-casino/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @primeyakubianape/spawn-grand-casino in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

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).

Build, test, and share
