It starts off okay: you need to solve the four grace engine Tetris puzzles on the floor, which powers the entire floor as a puzzle grid. Repeat this process, making your blue solution ever more elegant and your orange much more load-bearing, and you should then be able to run your blue slider to the door. The mysterious new puzzles are tricky each new solution must also be valid for every board before it.Īs for the bridge section, you'll need to enact a very elegant solution on the blue side, then hop back to the orange side to wall off whatever you can in the space allocated to you. On the second floor, you'll need to solve a terminal array of nausea-inducing colour puzzles, use a walkway-creating black white quarantine and coloured star puzzle to cross to the other side (here's one of several possible solutions), solve a terminal array with a brand new variant of puzzle, then use a slider on the same walkway board as the first to gain access to the door to the next room. You'll encounter symmetry puzzles change your perspective until you can see a clear path for just one of the sliders. Blue: climb through the detritus column using the gap on the left.Your cursor may be disconnected from the slider you need to click where it would be if the screen were in the right place. Yellow: the boards are off-centre, or move.Green: boards are masked in various ways, making it hard to see dots you need to hit and black white quarantines.The pink boards are hidden in the body of the column of detritus.From left to right, top row then bottom row: access to pink boards, access to green boards, access to yellow boards, access to blue boards, access to doorway. The puzzle solution gallery just below will help you get to the boards. Complicating matters, a pillar of detritus blocks your path - though not the progress of the slider - making it difficult to get where you need to go. The ultimate goal is the (locked) right hand door (looking over the room from the walkway board), but you'll have to power green, yellow, purple and blue cables to open it.

You need to access terminal arrays on both sides of the room, as well as two doors on the opposite side. Here's the set up: you have a simple black white quarantine board that creates a physical walkway in the room just below. Top floor - general goal and path layouts Let's tackle them in order - straight walkthrough, no messing about this time. These are fiddly and finicky, but persist and you'll get there the solutions are, as always, in the galleries at the very bottom of the page, where you can't accidentally see them.Īs you'd expect, given it's the final zone of the game, the Mountain is a long slog with several different puzzle sequences. Next, you have to hit three different solutions on the gird in order to open the door. You've powered this puzzle grid by firing up the lasers, but now you have to switch it on using the slider on the box being carried by one of the two central figures. So, you've lit up every laser on the island and think you're ready to face the ultimate challenge, eh? But also you're a bit confused and lost? Yes, this is very common and quite natural.Īfter making it to the peak, your first challenge is to activate the puzzles locking the entrance to the tunnels below. The Witness comes to a close when you dare to ascend the Mountain.
