Unlock! is a cooperative card game inspired by escape rooms that uses a simple system which allows you to search scenes, combine objects, and solve riddles. Play Unlock! to embark on great adventures while seated at a table using only cards and a companion app that can provide clues, check codes, monitor time remaining, etc.
In addition to the published scenarios, Space Cowboys has released several print-and-play scenarios that either have shorter playtimes that allow one to discover the Unlock! game system or have longer, more difficult challenges. In the words of a Space Cowboys representative, "Fifth Avenue and Doo-Arann are rather simple, ideal scenarios to discover the game. Elite is a bit harder. Ra's Temple is so hard that we didn't want to turn it into a full-fledged scenario; even with such a small number of cards, the usual time needed is comparable (or even higher) to the regular scenarios we sell. For experienced players only."
