KenR7A: I was super confused with this one. I still dont get it, honestly. I went through it 3 times just randomly choosing things and each time I got it to work somehow. I assume you have to light them all? I swear I clicked one that would have turned one off, but still completed the puzzle. *shrugs*
Also, there must be multiple ways to solve it. I remember ending on different ones during my random click fests.
I am bad at puzzles like this, so I looked it up. I can't explain "how" it works, other than each action has an effect on two others. One will light up, the other extinguish.
Since you posted after me, and say you had to get it randomly, maybe my tip above was inscrutable.
There are spikes pointing down from above each brazier. 4, 3, 7 and 4 refer to the number of spikes. Click the braziers in that order to open the door.
