15 Hardest Bonus Levels In Video Games

The Witness – The Underground Maze

Even getting to The Underground Maze is a question of journeying to the mountain, hitting a hidden switch and figuring out the solution for the panel inside. Upon entering the maze, you’ll face perhaps the toughest challenge the game has to offer, which is appropriately named “The Challenge”. You need to complete 14 puzzles focused on line-drawing – except they’re on a timer, which is indicated by a record player. The puzzles are different each time so you can’t note down solutions and keep retrying.
