Giant Rollercoaster #4 (Optional Puzzle)

Description
This is my fourth rollercoaster and this time, it also contains an optional (!) puzzle. That means you can do the rollercoaster without doing a puzzle. But if you want to do a puzzle, then there is one in this map. I'm very proud of this map. It took a lot of work (the puzzle itself took way longer than the rollercoaster, but never mind anymore), and the result is a nice rollercoaster with an optional puzzle which has a medium difficulty.

Here are the links to my other 4 rollercoasters:

Enjoy!

Great map.....figured out pretty early that 3 cubes where needed, was just a matter of finding them

You should have called this Excellant Puzzle (with optional giant rollercoaster)

Excellent map! The logic was challenging, but not as challenging as finding the fourth cube hiding in the shadows!

@Unowninator Just search for this map on Youtube. I already found one or two playthroughs that include the puzzle. Little tip for you: You need 3 cubes, to complete the puzzle, but 2 of them are hidden somewhere next / around the test chamber.

I can't figure out the puzzle. Is there a walkthrough/hint somewhere?

you should so do an outside rollercoaster

@apollosbeamship I don't really know why it cuts off the messages at random positions, I tested it several times and each time it was cut somewhere else. It says that I want to place my 5th coaster outside; then I tried that out, but it's quite difficult to do an outside rollercoaster, so I decided to do one more like I just did.

I still think I should remove that message button.

I pushed the button at the end of the puzzle , it was cut off "... ing the secret , the next roller coaster will take place on the su... " What does the full sentence say ? Anyway it was a great puzzle .
