TENANT ZERO

You are the IT administrator of a medium-sized company. The tickets don't stop. The users don't stop. The debt accumulates silently. You have ten shifts to keep the lights on.

What is this?

A single-file browser game built as a hobby project — something fun to make after work, for the people who live this job every day.

You play as an IT administrator managing a Microsoft 365 tenant under constant pressure. Each shift you draw a ticket: a real-ish scenario from the world of IT administration. Every choice has consequences. Some choices are bad. Some are less bad. None are free.

The hallway outside your office fills up with users. Slam the door to buy yourself time. Lose enough trust, blow the budget, or let security debt collapse into a breach, and it's over. Let eight users pile up outside and — well. That's also over.


How to play

Play it here — no install, no login, runs in the browser.

Or clone the repo and open index.html directly.

Meters

Meter What it means
Trust How much leadership still believes in you
Budget What's left to spend on tools and licences
Debt Accumulated security and technical debt (hits 100 = breach)
Focus Time and attention available this shift

The door

Users pile up outside your office. Left alone, they drain your focus. At 8 users, the door gives way and the game ends immediately.

You can slam the door at any time — costs 10 Trust, clears the queue. Use it wisely.

Choices

Each ticket has three options. Read the flavour text. They are not always equally bad. They are never equally good.


Scenarios include

  • A VP demanding an MFA exception for "productivity reasons"
  • A user who clicked a phishing link "to check if it was real"
  • The CFO who just emailed salary data to all-staff instead of all-finance
  • A USB drive found in the car park labelled Q3 SALARIES
  • A CEO impersonation email arriving while the actual CEO is making coffee 2 metres away
  • Payroll running on Windows Server 2008 R2. In 2026.
  • A developer requesting local admin rights for the sixth time this year (the tool is in the catalogue)
  • 47 stale admin accounts
  • And more

About

Made as a fun little side hobby — not affiliated with any employer, vendor, or standard body. The scenarios are fictional composites of recognisable situations. Any resemblance to your actual ticket queue is purely intentional.

Built with vanilla HTML, CSS, and JavaScript. No frameworks, no dependencies. Single file. Open source.


v1.2 — door on the left, users piling up, clock on the wall showing 21:47. You are still here.
