The Bunker Challenge was introduced by the TheFridGame channel, an interesting & quick challenge though very cruel. 8 Sims locked in a bunker: each assigned to different tasks like cooking, cleaning, repairing, and more.
Roles are chosen randomly with the help of the Spin Wheel, making every playthrough unique. Each spin decides who takes which role. The main rule: you can only play with one Sim per day. The Spin Wheel also decides which Sim you control today: you cannot switch to others.
