The search for the second activation crystal continues in the Machu Picchu Temple. You can see the crystal at the start of the temple, however, getting to it won´t be that easy.

Let´s clear the area, start with the symbols and see what the levers are for.

Once we set the corresponding boulders in their marks and pull the levers, the first gate opens. Yaay!
Now, let´s go deeper into the temple and open the rest of the gates.
Let´s see what´s behind the door on the left.
Here, we can see a puzzle with the shaped boulders, let´s put them in their places and see where it leads us.
Let´s start with the ones on the left and proceed further. There are more shaped boulder puzzles ahead and after a while, you´ll reach a lever. Once you pull it, the green gate opens and you can proceed with the shaped boulder puzzles on the right side.

After a few more shaped boulder puzzles, you´ll reach the second lever. Please pull it, unlock the brown gate and pull the final lever, which unlocks one of the three main gates at the beginning of the temple.
Once this part is done, let´s proceed with the entrance marked below.

In this area, there are four levers that need to be pulled in order to get to the main lever that opens one of the gates at the beginning of the temple. Let´s start with the puzzle in the upper right chamber.
There are four blue stones, three green stones and two white stones. To solve this puzzle, set the stones as shown here and you´ll be able to pull the first of the four levers.
Let´s proceed with the puzzle in the upper left chamber. We need to fill in the missing numbers from 1 to 4 so every number always appears only once in each red square, each column and each line. For a solution, click here and pull the second lever.
Let´s continue with the lower left chamber. Here, it´s necessary to open four gates to be able to pull the third main lever. To be able to do that, please place the stones on their places, pull the four levers and you´ll be able to pull the third main lever. The solution can be checked here.
Now, we can finish this area with the lower right chamber. The puzzle here is rather simple. Just place the stones on their places and pull the lever.
Once this is done, you can pull the main lever here and open the second of the three main gates in the beginning of the temple.
Now, we can proceed to the entrance shown below to complete the rest of the puzzles, open the last of the three gates and get the crystal. Let´s see what awaits us đ

Once we got through the door, there´s a math puzzle with stones numbered from one to eight. We need to match the correct numbers with it and place the fitting stone on the colored mark below. If you´re not sure, you can check the solution here.
This area is a little maze and the entrance below (as well as every entrance marked by the up arrow) will take you to the start (before the math puzzle) so let´s see what´s behind the door on the left.
As you proceed throughout this maze, it´s crucial to clear the area to discover the hints that will help you solve the final puzzle and open the third main gate.
After clearing this part and pulling this lever, you´ll discover numbers 682 with the hint.
When using the entrance on the left we´ll reach a room with a number on an island in the middle. The only thing we can do is pull a lever so let´s do that and return back. When going back, there´s we can see number 205 with a hint. The door on the left and the door below will take us to the start, therefore we´ll use the door up and enter a room with a number 614 and a hint.
From here, let´s use the door up (we´ll end up in the room with the number 682) and again up. Now, we can clear the room with the island and discover the number 738 with the hint. The upper entrance will take as to a room with water shown below.

The entrance on the left takes us to a puzzle room with colored stones.

For a solution, check this and let´s proceed up. We´ll end up in a room with four levers, four roman numbers in corners and a hint.
,
After pulling the levers in the correct order, the middle room opens and you´ll be able to see numbers 123 and a hint.
Then, after using the upper entrance, you´ll end up in a room with shaped boulders and when trying to go back from here, you´ll discover the final puzzle room, where, after entering the correct code, you´ll be able to pull the lever, open the third main gate and collect the crystal!

However, you still haven´t been in all rooms with hints, therefore, it´s necessary to find your way to the room with the water and use the upper entrance. You´ll end up in a room with a number 490 and a hint. From the room with the statue and number 490, use the upper entrance and you´ll end up in the last room you haven´t been so far. A room with a number 380 and a hint.
Now, with all the hints, you´ll be able to set the correct code in the final puzzle, open the third gate and collect the crystal đ
Also, should you lost your way somewhere in the maze, just always use the upper entrance and you´ll safely reach the end. Good luck adventurer!
