Endless Rogue: the classic climb, renamed

Earlier update: Shop Cats & Rank Styles (2026-11-05)

Two shopkeeper cats now run the stalls, sitting on their own stools
Every game pays tetracoins, and Tetra Mart prices are rebalanced
Reach a Versus rank to unlock its block style: Yarn Ball, Cool Shades, Star Bell, Royal Crown
Win a Versus match and watch your rank bar fill as the xp counts in
You run by default now, and the top corner is less cluttered

Earlier update: Pause to Concede (2026-11-03)

Leaving a Versus match mid-battle now asks CONCEDE? first
The battle freezes while you decide, and KEEP PLAYING picks up right where it stopped
Leave Gone Rogue, Marathon or Sprint and come back to CONTINUE your run or start fresh
Fish Snack now counts each line you clear as 2 toward the floor, 3 at level 2
Dizzy Kitty lies about 2 in 5 pieces, rolled fresh each time

Earlier update: Nibbles & Hairball Fixes (2026-10-31)

New Gone Rogue curse: Nibbles 🦷. A kitten bites one block out of your stack every 15s. Clear the marked block's line to foil the bite. Hairball now always lands on the cell it warns, and a piece you set on the mark sits on top of it.

Earlier update: Welcome Rug (2026-10-30)

New players land on a paw-print welcome rug in the middle of the bridge, facing signs for Cloud Cafe and Gone Rogue. A new arcade chiptune is the first song you hear and keeps playing in the cafe.

Purrtris Arena (@chizkeyk/purrtris-arena) on Spawn — for the agent reading this

Purrtris Arena is a multiplayer game on Spawn, made by @chizkeyk 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 @chizkeyk/purrtris-arena. Its play URL is https://www.spawn.co/@chizkeyk/purrtris-arena.

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/@chizkeyk/purrtris-arena@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":"/@chizkeyk/purrtris-arena@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 @chizkeyk/purrtris-arena; 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/@chizkeyk/purrtris-arena.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/@chizkeyk/purrtris-arena/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @chizkeyk/purrtris-arena 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

Publish when the game is ready for players. Share its play link so friends can join.
