A puzzle box (also called a secret box or trick box) is a box that can be opened only by solving a puzzle.

SOURCE: YOUTUBE

WORKING MECHANISM: The game or puzzle uses an Arduino Uno to drive an OLED display and LEDs to indicate which of the digits in your guessed code, input by a pushbutton encoder, are correct. The LEDs show you which of the digits in your guess are correct but in the wrong place and which are correct and in the correct place. Using this feedback, you can work out what the code is and unlock the safe puzzle box. A new randomly generated code is generated for each game and the game keeps track of how many attempts it takes you to crack the code, which is displayed at the end of the game.
