I had the same problem. I tried turning on the pillers in the order that that reapeared, In all combinations, and in different orders. Nothing worked. it has been more than an hour so I gave up once and started again the next day. Finally I figured it out! You have to light all four pillers in the order that they appear on the wall, from right to left. How stupid I was1 Why didn't I try that the first time! Don't make the same mistake!
