Yeti Yard

Newest update: Bring a Friend (2026-10-14)

• Bring a friend into your yard and a supply drop parachutes in for you as thanks. Share the link: the horde grows with your crew, and so do the rewards.

Earlier update: First Night Guide (2026-10-14)

• New players get a guided first night: gold arrows show you to build your first gun and chop a tree, and wave 1 waits until you're ready. The first three nights ease in gentler. Crows now come in big flocks for the flak to shred. Bring friends: share the link and the horde scales with your crew.

Earlier update: Arsenal & Armor (2026-10-13)

• Four new guns join your arsenal—magnum, pump shotgun, BAR rifle, and minigun—arriving as you level up, each hitting harder and faster than the last.
• Your weapon now scales with the horde: damage tracks the night's growing threat, and fire rate climbs with every level so you're never outgunned.
• Turrets transform as they level, gaining ammo crates, barbed wire defenses, and beacon lights all the way to level 30—plus a laser tower and snowplow truck join the fight.
• Snowmen drop 30% more carrots and 40% more coal, and the sweet spot shifts to a thick arrow that points at your target and moves as the tree takes damage.
• Recruiting neighbors now pays off: a third recruit costs less than another turret upgrade, and coal drains faster when your generator runs dry.

Earlier update: The Smooth Climb (2026-10-12)

• Night 1 snowmen are no longer a brutal gauntlet—the real challenge starts on night 2.
• Difficulty now follows one steady curve instead of sudden spikes, easing you in early then genuinely ramping up around night 8.
• Carrots and experience flow richer in the early game, giving you breathing room to build your defenses.
• Every harvest—yours, the lumberjack's, even the neighbors'—yields more in those crucial first nights.

Earlier update: Trophies & Trials (2026-10-12)

• Survive your first night and earn a trophy to prove it.
• Last through five nights and ten nights to unlock bigger, grander trophies.
• Slay a boss, reach level 20, fell a tree with a bonus, upgrade your house to level 10, or catch a supply drop—each feat earns you a trophy to display.
• Watch the new trailer to see what awaits in the Yard.

What players say

• @flickaboo · loved it · 2026-10-13 · played 1 hr 1 min · shown first by the maker: “The movement feels really responsive and smooth! I managed to make it to Night 4, and the game is pretty good. I think it would be even more enjoyable if I could play this with friends. Keep it up!”

  • @metalhorse233 (maker) replied 2026-10-13: “Hey, you can definitely play with friends! Just send them the invite link! :)”

• @kaya · needs work · 2026-10-12 · played 6 min · shown first by the maker: “did not expect my yeti to pull out a pistol and be badass like that lol. the start of night 1 wave 1 was doable, but it got overwhelming pretty quick and i really cant get the win on that. would be great if difficulty was scaled down”

  • @metalhorse233 (maker) replied 2026-10-12: “thank you!! the yeti's pistol is my fave too. just eased the early nights way down with more carrots and softer snowmen. come back and claim night 1 🪓”

• @moypi03 · loved it · 2026-10-14 · played 12 min: “I thought I'm playing ads at my phone hahahaha love how it goes and the movement feels so smooth.”

• @alongzera · needs work · 2026-10-13 · played 3 min: “there are no clear instructions on how to play the game and it will immediately load you into action. Would love to suggest a tutorial for new players to easily adapt into the game.”

Join and play, by yourself

This world is @metalhorse233/yeti-yard. Its play URL is https://www.spawn.co/@metalhorse233/yeti-yard.

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/@metalhorse233/yeti-yard@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 @metalhorse233/yeti-yard; 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/@metalhorse233/yeti-yard.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/@metalhorse233/yeti-yard/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @metalhorse233/yeti-yard 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 — 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.
