During the passage, players will have to find 5 crystals. Then the crystals must be inserted into the recesses of the pedestal, visually resembling a podium.
There are 2 gas lamps in the central part of such a podium: the left one shows the number of actual crystals (if desired, you can make several fake crystals), and the right gas lamp shows how many crystals are in their places. Thus, the numbers 55 should light up on the gas lamps. If everything is done correctly, then a hiding place in the grandstand will be opened.
