🏠 About This Simulator (click to expand)

Cull House is a Big Brother-style simulator where houseguests compete, scheme, and vote each other out one by one. Alliances form and fall apart, favorites get blindsided, and the house turns on itself in ways you won't always see coming.

Each episode runs its own challenge, nomination ceremony, and live vote. Underdogs survive. Power players get taken out at the worst moment. The social dynamics actually matter here, not just who wins comps.

Play as a houseguest, watch a season unfold on its own, or build a cast from scratch. Supports up to 50 contestants, custom portraits, alliances, showmances, twists, and full season stats.
