It’s good to see you back, fellow Junior Puzzle Operative! So, after you complete Puzzle 0604, you’re going to race up a water filled silo before starting Act 7 (and you can read my full guide on that if you’re struggling with Puzzle 0604). Once you get to Act 7, you’re going to go off course for a while, winding your way through the museum before ending back in the puzzle chambers.
While you’re at it, there are two missable Trophies/Achievements you can earn at the beginning of Act 7. I have guides to both of those, so click the links to learn more about those:
Okay, so now you should finally be entering Puzzle 0701 in The Entropy Centre. This puzzle is pretty easy, but I’m going to walk you through it nonetheless.
The trick really is to pick up the Entropy cube and hold it over the river (but don’t drop it in). Place the cube on the button, to open up the doors, then rewind it to the place where you were holding it above the river. Let it drop into the water, and it will end up floating to the next section of the puzzle. Now, just pick it up and place it on the button to complete the puzzle.
This one can be a little finnicky, because you have to get really close to the cube to pick it up, but if you get too close you’ll fall into the water and drown. So be careful.
Here’s a video of me solving Puzzle 0701:
Puzzle 0702 is slightly trickier, but it also makes use of the holding-the-cube-over-the-river trick. This time, though, it’s a jump cube that you want to toss into the water.
First, though, you’re going to need to take care of the wandering Entropy bot. I find it easiest to sneak up behind it and then toss it into a wall to make it explode, but you can also rewind its energy bolts if it shoots at you.
Once that’s taken care of, you want to move the jump cube onto one of the button pads. Then, pick it up and hold it over the river for a second. Don’t drop it in; just hold it there for a bit. Now, use the jump cube to spring yourself up to the next level. Here, you’ll find a cube. You’re going to want to drop back down and place this cube on the other button pad (not the one you put the jump cube on, but the other one), then use the jump cube to get back up to the second level with the cube still in hand.
Now, rewind the jump cube so it’s over the river, then let it drop in. Once it hits the wall on the other side of the water, place the standard cube on top of the pad that raises the bridge. This should create a path for you to spring over to the exit. Once you’re near the exit, rewind both cubes back to their positions on the bottom-level button pads, and you should be golden.
That’s a lot of information, so here’s a video of it all:
And that’s how you solve Puzzle 0701 and Puzzle 0702 in The Entropy Centre.
