The Squire Law Library has designed and run a series of popular escape room-style events, aimed at masters and undergraduate law students. Intended to prompt students to explore the full range of legal resources available to them, the games typically challenge participants to open a locked safe: relying on legal databases, the library catalogue and print materials to decipher a six-digit combination. This article, based on Lizz Edwards-Waller's presentation at the BIALL (virtual) conference 2020, reflects on the practicalities of running and promoting code-breaking events within the library and considers the benefits of this style of event in addition to, or instead of, more traditional law library orientation tours.
