4 Dial Combination Box
You will need the blue piece of paper from the drawer at the bottom of the stairs to solve this puzzle.
This puzzle clue does not require any counting or mathematics. You do not need to add any numbers together. Press the latch above the dials when you want to test if the current combination is correct.
The left column of numbers on the clue sheet is the key. Each of the other columns represent the dials as you see them in front of you.
Going down a column of numbers, the answer for that dial is where the number in the row matches on the far left. So the answer for the first dial is 3.
