What players say
@makeriffic · loved it · 2026-10-20 · played 6 min: “Wow this game is very tricky, at first I thought the game was all about stacking the boxes on top of each other, then I realized I can maximized the space around instead. It's actually hard to fit all boxes inside. Especially with the crane's motion.”
@jeon · loved it · 2026-10-20 · played under a minute: “Haha, this is fun! 😂 The gameplay feels unique, and I just want to keep going! I managed to stack 13 boxes, and now I’m aiming for that #1 spot. Let’s gooo! 🔥🏆”

This world is @tensaistudio/lucky-stack. Its play URL is https://www.spawn.co/@tensaistudio/lucky-stack.
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/@tensaistudio/lucky-stack@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 @tensaistudio/lucky-stack; 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.
