Along the grand impressive wall, there is a short and narrow opening. There’s also mist coming out of the opening that leads to darkness, will you take the chance and embark on the adventure?

Upon entering the room, the players discover a coffin in the center of the room, three cushions, and several gigantic stone plates.

Someone finds a riddle on top of the coffin, it reads, “Bow down sincerely in the presence of your highness, speak no more”. Removing their ability to communicate verbally, the players kneel faithfully at the cushions.

Suddenly, stone plates come forward sequentially, emphasizing specific hieroglyphics on them. The movement of the stones produces a loud grinding sound, catching the attention of the players.

Someone recognizes that the hieroglyphics on the coffin match with those appearing on the wall. They then devise a plan, through hand motion, to divide and conquer.

pissss… sissssssss…… wheeeeewwwww… the coffin lid opens and the room comes alive at the presence of the awoken pharaoh. There’s wind, sounds, and rise in temperature.

This room requires a combination of physical activities and mental observations to create an authentic and immersive experience. On a logistic level, each gag of the room auto-resets immediately because they all require physical human inputs, such that when the human is no longer engaging with it, then it will shut off. The room requires very little maintenance after each group because nothing in the room physically displaces. The difficulty of the room can be adjusted by changing the number of hieroglyphic characters to show.

Built with gigantic Egyptian limestone, the facade of the room resembles that of a dilapidated ancient pyramid. A few stone bricks seem to have fell, creating a small opening for exploration. There are also streams of mist shooting evenly out of the crevices near the opening, generated by a smoke machine housed inside the brick.

Here is the desired texture. The bricks are carefully arranged to fit with occasional cracks in between.

Here is one simple DIY fog maker, using dry ice, a fan, and a battery. This can be housed inside the gigantic bricks and release the smoke through the cracks.

As the centerpiece of the room, the sarcophagus provides a sense of mystery and awe. The first clue actually rests on top of the top of the coffin, which provides a riddle to prompt players to pray respectfully at the cushions. This reveals a special message in hieroglyphics on the wall. The players then have to recognize the hieroglyphics on the coffin, and push the message at once. When the players finally solve the puzzle in 3D twister style, the restless Pharaoh will be awakened to finish his last wish. This effect is created with a few components, including a pneumatic cylinder to slowly lift up the top at an angle; an air compressor to release air from within the coffin, producing sizzling sound and actual air; lastly, bluetooth transmitters to turn on random soundless fans in the room, to create the effect of a spirit roaming around.

Here is the pneumatic piston that will push the lid vertically at an angle for precisely 12 inches.

TURN ON VOLUME! When the lid opens, the room will cooperate and produce creepy sound and wind effects.

At start, the wall plates are filled with an overwhelming amount of hieroglyphics. Then when the players solve the first riddle by kneeing at the cushions, the plate will activate and mechanically reveal a dozen specific hieroglyphics characters. This can be achieved with the classic split-flip displays, which was hugely popular back in old train stations. This step will require a huge amount of cooperation. The message will only display when all three cushions feel a certain force, so either one player stays and tries to sit on all of them, or they divide the task and have each player remember some part of the wall. The wall is purely a display unit.

I envision the plates to move in and out with a similar effect as the moles in Whack A Mole. The two options are electromagnetically controlled springs that push the bricks or gas pistons, both of which are commercial technologies.
