Chapter 2: Order and Chaos
Please read the rules for this challenge HERE
Submission thread will be opened once all Chapters are out
I moved the stones in the correct order and suddenly... a dull sounding "clack" appeared from within the wagon door. I walked to the door and pushed the handle. The door opened. And as I walked into the second wagon, I found myself in a chamber of chaos... There were no better words to describe what I was seeing. "Hello?!", I shouted hoping that whoever this "Master of Secrets" was, would be there. My shout was answered by nothing but the rattling noise of the train, as it continued its seemingly endless trip through the darkness. Desperation overcame me. "Is anybody here?!" I shouted even louder hoping that there would be someone in any of the other wagons. Hell, or anywhere. I walked straight through the mess towards the next wagon door of yellow color. And again... locked. This time there were no indications on the door. However, it looked like it had the same mechanism as the previous door. Just like the abacus served as a switch to open the previous door, this door also must have a switch. I looked at the garbage all over the wagon again and noticed something interesting: Despite all the chaos around me, there was some sort of order... Both sides of the room looked perfectly symmetric... Apart from some small details. Maybe those small details would help me find the switch, in order to unlock the yellow door to the next wagon...
Task: Identify how many differences there are between the left and the right side of the room
