Play The Lost World — an interactive story where YOU are the hero

after the classic by Arthur Conan Doyle, 1912

Join Professor Challenger's expedition to the plateau where evolution forgot to stop. Photograph the impossible, survive the ape-men and the pterodactyl rookery, and get the evidence home — with the bridge behind you cut.

A moment from one playthrough

The single tree-trunk bridge back off the plateau lies in splinters in the abyss — Gomez smiles at you from the far side before he vanishes into the trees. Behind you, something big moves through the ferns. Follow Challenger deeper to find another way, or make camp and fortify?

Live The Lost World, don't just read it

In this interactive telling of The Lost World, you don't read about the hero — you are the hero. The Storyteller keeps Arthur Conan Doyle's world true to the original — its characters, its places, its mood, all held as canon — then narrates every scene aloud and draws the moment you're in as an ink illustration. You type or speak what you do next, and the world answers: it remembers the promises you made, the things you took, and the people you crossed. Follow Arthur Conan Doyle's plot faithfully, or step off it and watch a brand-new version of The Lost World unfold — one that still reaches a real ending.

How it works

The Storyteller holds the world of the book as canon — its characters, places and mood — and opens with you as the hero.
Type or speak anything: the world reacts, remembers, and stays true to the original's spirit.
Every playthrough is a brand-new story. Follow the plot — or break it and see what happens.
