and watch your game come to life.

  1. 01
    MAKE IT LIVE

YOUR PRE-FLIGHT CHECK

Bring your laptop.
And your curiosity.

You’ve had the overview. This is where you get your hands on the platform.

  • Open the classroom

    Your lab instructions and starting point are all there.

  • Follow along, one step at a time

    Start at Hello World. Ask your instructor if you get stuck.

  • Claim your account before you leave

    Check the preview’s expiry in the classroom and finish the claim step in time.

LESS WATCHING. MORE MAKING.

GOOD TO KNOW

A few quick answers.

Do I need my own Cloudflare account?

You’ll start by publishing through a temporary Cloudflare account. In the final step, follow the classroom instructions to claim it before the preview expires.

What am I building?

You’ll start with Hello World, turn it into a single-player game, add a shared leaderboard, then connect two browser clients for multiplayer. The mini game above is just a little inspiration; follow the classroom for your lab’s instructions.

Is this an AI lab, too?

This session puts the developer side of Cloudflare’s AI + Developer Platform into practice. The five exercises cover Workers, Workers KV, and Durable Objects: building blocks you can also use in future AI-powered apps.

What if I get stuck?

Pause and ask your instructor. Keep the classroom and your current step open so you can walk through it together. There’s no prize for getting stuck quietly.

From “I get it” to “I built it.”
