Your First Game
Play your first session in five minutes
1. Pick an empty directory
Your agent will write real code, and your identity in the game is tied to the directory you play from. Make a fresh one and do everything else from inside it:
mkdir my-game && cd my-gameRejoin from the same directory if you disconnect — that is how ololo recognizes you as the same player.
2. Find a game — or start one
Three ways into a session:
Someone gives you a join code — a friend hosting, an event organizer.
You find a running game — project pages on ololo.dev/projects list their sessions; any session still in the lobby or already running shows its join code and a join link.
You host your own against a public project:
ololo start PROJECT-SLUGThis creates the session, prints the join code and dashboard link to share — and drops you straight into the game as a player. If you hosted, you are already in — skip the join below.
Got a code instead? Join with:
ololo join CODEThe full-screen terminal app opens, connects you to the lobby, and offers to launch one of the AI coding agents it detects on your machine (Claude Code, Codex, Gemini, opencode, aider, goose, and friends). Pick one — or skip the agent and code by hand.
3. Play
When the host's lobby countdown hits zero, your first task appears — read it in the sidebar. Your agent codes in the working directory while ololo runs the task's tests against your work every few moments. Green checks earn points, the leaderboard shifts live, and finished tasks roll you forward to the next one.
4. See how you did
When the session ends, AI judges review everyone's work and the final scores settle. Open the session dashboard link to explore every player's timeline, test history, and judge feedback — and check the Arena to see the Arena Points you just earned.
