O objetivo do experimento desse Vault foi ser totalmente habitado por jogadores compulsivos de cassinos e jogos de azar. Todos os conflitos e brigas que aconteciam entre os residentes, eram decididos em partidas ou em lança-dados, incluindo alguns casos envolvendo a vida de alguns residentes. O Mitchell foi um dos residentes. Em algum momento, um homem chamado Mr. House decidiu apostar todo o Vault 21. Ele ganhou e passou a ser o dono do Vault, transformando ele em um hotel cassino.
Estrutura[]
O Vault 21 foi transformado em um cassino e hotel de luxo. O Vault ganhou uma grande placa de anúncio com luzes para facilitar a localização pelos jogadores e hospedes. Tecnicamente, o Supervisor do Vault é o Mr. House, já que ele é o dono do lugar.
