IT one-sheet: network requirements.

Everything needed to run the simulation on a school network, on one page.

1 · Domains to whitelist

Allow these domains through the school's web filter and firewall. All traffic is HTTPS.

thebusiness.schoolWebsite & teacher resources

play.thebusiness.schoolThe simulation itself — students & teachers

*.thebusiness.schoolSimplest rule if wildcards are supported

fonts.googleapis.com · fonts.gstatic.comWeb fonts (usually already allowed)

2 · Connections & bandwidth

HTTPS, port 443 only

Standard secure web traffic. No custom ports, no VPN, nothing to install.

WebSocket connections

Live gameplay uses secure WebSockets (wss://) to the same domains. Most filters pass these; if the game stalls behind a proxy, allow WebSocket traffic to play.thebusiness.school.

Light bandwidth

Text and small data updates — no video streaming. A full class of 32 runs comfortably on ordinary school Wi-Fi.

EU cloud hosting

Sessions are managed server-side in the EU. No peer-to-peer connections between student devices.

3 · Devices

Any device with a modern browser: Chromebooks, Windows/Mac laptops, iPads and phones. No installation, no browser extensions, no admin rights. Recent versions of Chrome, Edge, Safari and Firefox are all supported.

4 · Accounts & data

Students never create accounts. They join a session with a 6-digit PIN — no email, no password, no personal data collected from minors. Only the teacher has a login.
