Boy Johnny went with his dad in a game, "Johnny Test: Problem Dad" in the dungeon. There he will teach his system encryption. Each level will represent a room with a closed door, which is needed to crack. Time is not given a lot, so be careful. To pick a lock, you need to look at the sequence of flashes that will be left on the screen and remember them. Then repeat the sequence, and the door will open. At higher levels, the combination will be more difficult.
