Room for one more

Newest update (2026-09-10)

• Hints now follow one verified solution throughout each arrival, with named clickable destinations and clear swap guidance. Restored the missing fern and lamp models. All nine puzzle rules and saved progress are preserved.

Earlier update (2026-09-10)

• Help now opens a quick tutorial. More reliable tile taps and selection, automatic recovery for missing guest models, and a separate saved cabin for each player. Reduced repeated UI work and redundant soundtrack commands while preserving the cozy visuals, music, puzzle rules and existing creator progress.

What players say

• @jissi · 2026-09-11 · played 2 hrs 25 min: “I like the puzzle, it kept me coming back to it for minutes on and off. I love the background music too. I feel like more could have been done through making the characters move. Reactions towards each others, and adding more clarity. I struggled a bit at first though but overall, a good concept and prototype :)”

• @jeon · 2026-09-10 · played 2 min: “I like the game for being a puzzle game, its really unique and a nice idea bro. The background sounds are satisfying and the environment fits the game really well too. I enjoyed figuring things out while playing, keep working on it and looking forward to seeing more!”

• @makeriffic · 2026-09-10 · played 15 min: “Nvm. I got to Tansy but here I am really stuck lol.”

  • @gamebert (maker) replied 2026-09-10: “its a pretty tough game, I just made an object repair and added hints that point towards one of the valid solutions, thanks for trying!”

• @makeriffic · 2026-09-10 · played 15 min: “Welp, I guess I am stuck here lol. I really like the puzzle on where to place them based on their needs. But I am really struggling and loving the challenge at the same time. I can't somehow think of a way to place Luma with the Lamp while meeting the needs of Pip and Bramble. I don't know if the tiles are enough or if I am just bad at this game haha.”

Join and play, by yourself

This world is @gamebert/room-for-one-more. Its play URL is https://www.spawn.co/@gamebert/room-for-one-more.

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/@gamebert/room-for-one-more@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 @gamebert/room-for-one-more; 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/@gamebert/room-for-one-more.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/@gamebert/room-for-one-more/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @gamebert/room-for-one-more 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).
