UNLOCK: The guessing game

In UNLOCK, 1 to 6 players compete to unlock the hidden smartphone-unlocking code created by another player called ‘The Lock’ by a series of attempts. The lock player will give players information about how close they are to the hidden code on each attempt. When at least one of the players finds the secret code, the one that did best in the unlocking attempts will win the game.
