The Lantern Below20–30 minThe Carrow Point light went dark three nights ago and its keeper vanished. Go down into the flooded smugglers' cellar beneath it, find the lamp's crystal heart, and light the beacon before the storm fleet reaches the rocks.The Midnight Mechanism20–40 minThe Vessel Square clocktower has sealed its doors, and its brass automatons have woken. When the great bell strikes midnight, the gears will grind the tower shut for good. Climb through the turning labyrinth, recover the Mainspring Key and set it in the bell's escapement to stop the clock.Silence on Kestrel-920–40 minResearch station Kestrel-9 hangs in orbit above a banded gas giant, silent for eleven days. Your shuttle is crippled and the station is your only hope. Fight past rogue drones, cross a vented section, find the beacon core, and relight the distress beacon.

What makes this different from asking a chatbot to run a game?

A chatbot improvising an RPG forgets your inventory, fudges dice and invents whatever the story needs. Here the AI only narrates. The Games in Chat engine owns the map, your HP, every item and every roll, and it shows them after every action, so a long game doesn't drift.

How do you play?

Say what you do in plain words: go north, search the desk, use the oil flask on the eel, ask the keeper about the vault. The game master turns it into an action, the engine resolves it with a d20 check where needed, and you get the result and your full status.

Where can you play?

Here on the web (free: the Daily Mystery and three adventures, 60 narrated turns a day; Plus opens the rest), or inside Claude and ChatGPT once you add Games in Chat, where your chat's own AI is the game master. A save code moves a game between them.
