100 Doors of Revenge is a new puzzle game from Gipnetix Games, the creators of 100 Doors 2013 and 100 Room. It is considered a sequel to 100 Doors 2013 and is played in the same way. Your goal is to solve the puzzles to unlock the door and travel up to the next floor. As of this post there have been 24 Doors released for 100 Doors of Revenge. Below is a walkthrough for each level.
Level 41 / Door 41 Answer: Enter the combination “56792335” on the keypad. How we solved it: Find the upside down numbers (including the “9” in the picture frame) and arrange them in order from least to greatest (hint on the floor). The numbers are 5, 6, 7, 9, 23, 35.
Level 42 / Door 42 Answer: Enter the combination “90454560” on the keypad. How we solved it: Figure out the angle measurements for the light blue corners of the shapes from top to bottom. (90 degrees -> 45 degrees -> 45 degrees -> 60 degrees).
Level 43 / Door 43 Answer: Turn the volume of your device all the way up (the clue above the door tells you to “play your music loud”)
Level 44/ Door 44 Answer: Continuously swipe the two grey bars in a left to right direction until they are free of the metal plating on the door. It takes quite a few swipes.
Level 45 / Door 45 Answer: Enter the combination “76491789” on the keypad. How we solved it: A Knight chess piece moves over one space, and up/down 2 spaces. Look at what direction each Knight piece is facing and find the number that it would land on if it were to move (start from the top piece)
