Big Brother Simulator — or the Real Thing?

Simulators show you a season. We built the version where you're actually in it — scheming against 8–12 real people who are scheming right back.

The best Big Brother simulators

Credit where it's due — if you want to simulate a season, these are the classics:

BrantSteele Big Brother Simulator

The genre's beloved standard for over a decade. Cast anyone — friends, celebrities, cartoon characters — and watch a full season generate itself, complete with competitions, nominations, and messy jury votes. Endlessly customizable, endlessly rerunnable.

Cull House

A newer fan-made simulator where you make the calls — nominations, challenges, and social moves — and steer the season to the finale. More hands-on than BrantSteele, still single-player.

Both are free, browser-based, and great at what they do. But they share one limit: every houseguest except you is generated by the program. Nobody is actually plotting. Nobody actually feels betrayed. And that feeling is the entire show.

What a simulator can't simulate

Reality Rivals: Online is what happens when you replace the simulated cast with 8–12 real people. Real alliances form in the Living Room. A real House Captain takes power. Real safety competitions decide who's protected, a real Targeting Ceremony puts targets on real backs, and a real vote sends someone home — a person who will absolutely remember what you did. At the finale, a jury of your evicted rivals decides whether your game deserves the win.

Frequently asked questions

What is a Big Brother simulator?
A program that auto-plays a full Big Brother-style season — you set the cast, it generates the competitions, nominations, evictions, and winner. BrantSteele and Cull House are the best known.
Is there a version with real people?
That's us. Reality Rivals: Online runs live matches of 8–12 real players with alliances, safety comps, a Targeting Ceremony, and evictions until one Regent Rival remains. First match is free, in your browser or on iOS.
Is Reality Rivals official Big Brother?
No. It's an original, independent game inspired by social strategy shows like Big Brother, Survivor, and The Traitors — not affiliated with or endorsed by CBS, Banijay, or Endemol Shine.
