The door locks behind you. A large menacing timer begins counting down from 1 hour. You’re not sure where to begin. You just know you must escape the room before the timer reaches zero. You know the key to the exit is in the room, but how do you find it? You slowly begin searching the room. Locks are everywhere. You find a clue in a drawer. You realize that the solution is a number. Is that number the combination to one of the locks? Your pulse quickens. The number does indeed open a lock. The lock was hiding another clue. A friend or yours, or maybe even a stranger shouts out that they found a clue in a different part of the room. A clue that integrates with the clue you just found. The timer is still counting down.
