Just curious, how did you or how were you supposed to figure it out, because I was stuck there for the longest time? Though I'm not known for my puzzle-solving skills so I was probably missing something.
To figure this out, you needed to observe the behaviour of the crystals when you clicked on them, and write things down. After that, it's a matter of logic.
When you try clicking on the crystals, four trigger another crystal, one doesn't, and one crystal is never triggered by another. Given that, there are only two possible combinations: follow the order in which the crystals trigger each other (beginning with the crystal that isn't triggered by another, and ending with the crystal which doesn't trigger another), or the reverse order.
The reason why so many people were stuck on this puzzle was a slight implementation problem that caused the right combination to not work under certain conditions (see other threads on this topic).
