Mansion 2048 is a new room-escape puzzle game from Gipnetix Games (developers of 100 Doors 2013 and 100 Doors of Revenge). Available on the iTunes App Store for iOS devices (I assume also coming to Android via Google Play), the game offers a brand new mysterious mansion filled with new puzzles and mini-games for you to complete. Below is a complete walkthrough for each level of Mansion 2048.
Level 5 / Door 5 Answer: Challenge Room: Get the key to the exit by moving the blocks.
Level 6 / Door 6 Answer: Using one of the hint systems will automatically complete the level (Tutorial complete).
Level 7 / Door 7 Answer: Slide the grey pillars to the side walls until they completely disappear. Go through the door.
Level 8 / Door 8 Answer: Tap and hold the left circle gear until the gate raises halfway up and then stops. When it stops, tap and hold the right circle gear until the gate is completely up.
Congratulations! You’ve completed levels 5 through 8 of Mansion 2048. Continue to levels 9 through 12.
