+# WebGames Dataset
+
+This dataset contains a collection of challenges designed for evaluating general-purpose web-browsing AI agents.  The challenges are designed to be easy for humans but difficult for AI agents, and they are fast and simple to run using client-side state and a single-page JavaScript application. Each task provides a unique password upon successful completion, facilitating easy evaluation.
