100 Doors 2013 (not to be confused with 100 Floors) is the sequel of the one of the most popular puzzle games, 100 Doors. The game features 100 Doors with different puzzles to solve. It is available for Android devices. Below is a guide and walkthrough for each of the 100 doors in 100 Doors 2013.

Level 71 / Door 71 Answer: Enter the code “17618354” in the keypad. How we solved it: Insert the numbers above the door into the “?” to complete each pattern. Then add up each column (clue from the “+” signs on the ground)

  • The first column numbers can all be divided by 4.
  • 1st column: 4, 12, 24, 36, 48, 52 = 176
  • The second column numbers can all be divided by 3.
  • 2nd column: 9, 27, 33, 69, 6, 39 = 183
  • The third column numbers can be divided by 1 and itself.
  • 3rd column: 1, 11, 13, 5, 7, 17 = 54

Level 72 / Door 72 Answer: Pick up the crowbar (on the wall to the left) and the screwdriver (on the ground below the crowbar where the wall meets the ground). Use the crowbar on the white electrical box on the right wall, then use the screwdriver on it, you’ll get a key in your inventory. Press the keypad and use the keycard on it.

Level 73 / Door 73 Answer: First solve for the “?” around the circle:

  • 1, 3, 5, 7
  • 9, 12, 15, 18
  • 2, 4, 6, 8
  • 22, 33, 44, 55

Using the key to the right, you’ll see the red line means you add the two numbers and the green line means you multiply the two numbers. Move the lines to point at the correct numbers that equate to the numbers of the code above the door.

The first is 30, so move the green arrow to point at the “?” that would be a 5 and the “?” that would be a 6 and press calculate so it multiplies them. Next move the red arrow to point at 22 and 9 and press calculate so it adds them. Move the red arrow to point to the “?” that would be 33 and 12 and calculate. Move the green arrow to point to the “?” that would be 15 and 44 and calculate to multiply. The door should open.

Level 74 / Door 74 Answer: Press the left and right arrows to move the handles so the safe bars will move. Press the arrows in this order:

  • Right 3 times
  • Left 7 times
  • Right 6 times
  • Left 9 times
  • Right 12 times
  • Left 6 times

Level 75 / Door 75 Answer: Enter the code “1275” on the panel. How we solved it: The code is hidden in the numbers on door. Scattered throughout the numbers on the door are a bunch of 1’s that form the combination for the code.
