These games offer the "escape room" experience in the comfort of your own home. Most use a system of cards to disperse the puzzles and clues, and all include some sort of helper mechanism if you get stuck. And just like a live-action escape room, these are generally one-shot experiences. They are good to re-gift or pass among your friends, except for the "Exit" series of games, during which you will likely cut, fold, and generally destroy the components as you play the game. Also note the "Unlock" series will require the use of a free app that is used to regulate the time and puzzles.
