Fairly rare LCD game (although I'm told nearly 50,000 were produced). There are two ways to play: Maze and Adventure. The object of Maze is to escape out of a maze, and there are 1000 different ones to choose from (you enter the number of the maze you want to try). Adventure is the same, but you must first recover 3 artifacts from within the maze (hence the 'treasure quest'). Game play is first-person (sort of Doom like, or that maze like screensaver that was common in Windows operating systems.) Certain ranges of maze numbers have different sized maps (maze #'s 000-599 are on an 8x8 grid, 600-699 are on an 8x9 grid and so on). Check out the manual available online for a map of 5 of the mazes. Entex renamed this game to Treasure Quest in 1982 for a re-release, but I'm not certain if it ever actually got released under that name.
