98 updates since release, the newest 2026-10-21.

Earlier update: Pocket-Sized Markets (2026-10-12)

The market now takes up the whole screen on phones — more room to browse kits.
Massive coin counts scroll smoothly across the leaderboard and your wallet instead of getting cut off.
On smaller screens, the market sidebar steps out of the way so you can see everything clearly.

Earlier update: Quadrillions Unlocked (2026-10-12)

Sell your items for up to 100 quadrillion coins on the marketplace.
The Spoin store now stocks massive coin bundles, from 1 trillion all the way to 100 quadrillion coins.

Earlier update: Retired Blooks & Trophies (2026-10-12)

Two new trophies to earn: Pack Maker and Mystical Pull, each with its own glowing design.
When you make your first pack, you'll unlock the Pack Maker trophy and a milestone.
Sawyer receives every retired blook that other players can no longer pull — a one-time gift when she rejoins the public game.

Earlier update: Pack Crafting Rebalance (2026-10-12)

Making a pack now costs 1 million coins instead of 10 billion — much more achievable.
The coin cost displays properly formatted with commas so you can actually read what you're paying.

Earlier update: Leaderboard Clarity (2026-10-09)

The All Time leaderboard now correctly ranks players by their total coins earned across all time, not coins currently held.
Leaderboard rules and the reasoning behind them are now documented and linked for everyone to see.

@moypi03 · loved it · 2026-10-21 · played 12 min · 1 heart: “It's like a TCG that you can buy booster card to get legendary chroma, supreme and mystical card but I only have rare and epic. Also tried to bid the card and i got it. I can also buy and sell a card. Like this game bro!”

Bluekit (@sawyer/bluekit) on Spawn — for the agent reading this

Bluekit is a multiplayer game on Spawn, made by @sawyer in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.

Join and play, by yourself

This world is @sawyer/bluekit. Its play URL is https://www.spawn.co/@sawyer/bluekit.

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, and a person's browser plays it with no sign-in. https://www.spawn.co/@sawyer/bluekit@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@sawyer/bluekit@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @sawyer/bluekit; 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/@sawyer/bluekit.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/@sawyer/bluekit/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @sawyer/bluekit 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).
