The premise of this game is that it was invented by the ancient Egyptians. Its a Tetris like game that includes shapes with bricks cut in half diagonally. This makes it extremely difficult to build a row. It could have been better titled "Curse of the Bricks". The description of the game on the back of the box is uniquely laid out in the shape of a triangle. Despite the official description, pieces function like the original Tetris bricks and cannot be "twisted" into place.

While there is proof that AVE published this game in the USA, its possible Thin Chen Enterprise did so also. There are 72-pin NES carts in NTSC format of this game marked Sachen, but no proof they were sold in the USA. Thin Chen Enterprise did however, file a US patent for the game, which makes a US release much more likely. Also, Thin Chen Enterprise Company, Ltd (Sachen) registered a US copyright (TX-3-038-106) 1990-06-16 for "Pyramid I" and recorded that the work was published on 1990-07-10 (the Japanese publishing date)

The Hacker International version includes nudity but is not immediately distinguishable from the other famicom versions. Usually they have a blue & gold label.
