A rusted iron door stands at the far end of a ravine, engraved with a closed eye. Behind it, the dungeon of the sorcerer Malgrim, who takes a tribute from the village of Pierrebrune every single year. You have agreed to go down there. Welcome to the Iron Dungeon, a choose your own adventure AI gamebook from Yiaho, free and with no sign-up: the numbered paragraphs are replaced by the narrator’s choices, and the thrill is exactly the same.
The narrator runs on GPT-5.6 Luna, a recent OpenAI model, with game rules written by Yiaho. It simulates six sided dice, announces every roll and keeps your adventure sheet up to date, like a role play bot on Character AI, in English and in a setting that stays suitable for everyone.
The story: the dungeon of the sorcerer Malgrim
Before you go in, you pick your equipment: sword and shield, bow and rope, or lantern and a bag of provisions. The dungeon has about fifteen rooms: goblin guards, a bridge over a chasm, a library of riddles, the kitchen of a vegetarian troll, a mirror maze, the treasure room and Malgrim’s laboratory. Three riddles mark the way down, and two key items, the silver key and the amulet of the open eye, let you defeat the sorcerer without a fight. The finale rewards cunning.
Skill, stamina, luck: the rules of this choose your own adventure AI
If you grew up with a pencil, an eraser and two dice sitting on a gamebook, this choose your own adventure AI will give you that thrill back; if you did not, one minute is enough to learn it. At the start, the narrator rolls your three attributes: Skill, one die plus six, your ability in a fight; Stamina, two dice plus twelve, your hit points; Luck, one die plus six, the favour of fate. In combat, each round is played with one roll per side, two dice plus Skill: the lower attack strength loses two Stamina points. Testing your luck means rolling two dice: a success if the total is less than or equal to your Luck, which drops by one after each test. Provisions restore four Stamina points. The adventure sheet notes your scores, gold, provisions, items and clues. At zero Stamina points the adventure ends and the narrator offers to start again.
How to play
Give your first name and the narrator announces your scores. After that, answer with a number or write freely, for example *I search the library* or “I offer to cook with the troll”. Ask for your adventure sheet at any time, keep provisions for the bad rolls, test your luck sparingly and search every room. The narrator remembers everything you tell it during the game.
What the narrator does, and what it will not do
Fights stay stylized, with no blood and no cruelty, in the tone of an adventure tale for everyone. The dungeon, its creatures and its items are original: nothing is taken from an existing series or title. If you sincerely ask it what it is, the narrator will tell you that it is an artificial intelligence running a game. Your browser keeps the game in local memory until you click Clear, and Yiaho keeps nothing on its side.
