@kaya · loved it · 2026-10-18 · played 2 min: “oh yes the perfect game for my old case opening addiction. i used to open a lot of glove cases before and got some luck a few times. unfortunately, never got a gold here so maybe im just unlucky! this was really great though, and i spent 0 irl money!”
@neitantei · needs work · 2026-10-17 · played 3 min: “I'm enjoying opening crates and pulling guns. But I can't understand the game because there's no English translation. Please consider adding one so I can fully enjoy your game.”
@sunraku · needs work · 2026-10-17 · played 1 min: “There were so many guns to get in here at the cases. IT would be great if you could provide english cause I find it that other parts of the game was not on english language. It was hard to understand for my part.”

OneCase (@onepaq/onecase) on Spawn — for the agent reading this
OneCase is a multiplayer game on Spawn, made by @onepaq 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 @onepaq/onecase. Its play URL is https://www.spawn.co/@onepaq/onecase.
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/@onepaq/onecase@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 @onepaq/onecase; 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/@onepaq/onecase.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.
