The ‘L’ shaped platform has five different, colored shapes on the puzzle. As with the others, you need to leave the exact room for each shape. There are two solutions – one will make the platform turn anti-clockwise, and the other clockwise. Now, you need to turn it clockwise.
Next, head forward past the steps to a set of puzzles on your right. These are slightly trickier, so see the solutions below. After you have completed them, continue on towards the dock. When you get to a fork in the path, take the one furthest to the right until you see a puzzle on the ground. Then, head back the the stairs that go underground by the ‘L’ shaped platform. Here, you will see five puzzle with yellow and blue shapes. The rule here is that blue squares eliminate yellow squares in the shapes you are attempting to draw round the puzzle. Don’t forget that the previous rule still applies.
Solving the previous set of puzzles will allow you to go down the stairs near the beginning of the marsh area, just after the first moveable platform. See the solutions below. After, head to the stairs just before the ‘L’ shaped platform. This will open up a door on the other side of the room to a red structure – the final part of the marsh area.
