Unlock is a series of cooperative card-based escape adventures for up to six players. Each Unlock game consists of sixty cards depicting objects, maps, and puzzles that can be activated, solved, or combined in an effort to access other cards and areas. The free companion app tracks the time allotted to win the game, while also offering hints and unlocking new, and necessary, elements. When the players believe they have figured out the code to escape each adventure, they will input the number into the app and escape the danger, or lose even more time in finding the real sequence. Once you have completed the adventure you will be presented with a rating. Your rating will be determined by your use of hints, incorrect guesses, and the duration of your game. Every play of the game will get you closer and closer to that perfect run and a five-star score, so don't dismiss your defeats, for every mistake may be the key to your success the next time around Each box includes a ten-card tutorial deck so even those less experienced in the art of escape can dive right into the game experience.The tutorial briefly introduces each of the game's different card types and interactions so every player knows just how to take advantage of the cards in the game. Please note that the tutorial deck is included within the first scenario deck.
