Daedalian Opus (alternative title Puzzle Road) was a puzzle game for the Game Boy released in June of 1990. It was one of the few games produced by the little-known software company Vic Tokai.
The game is essentially a series of jigsaw
puzzles with Tetris
-like pieces known as pentominos
that must be assembled into a specific shape. The puzzles start off simple, with the shapes being comprised mostly of rectangles and having simple solutions, but the puzzles quickly grow more complex, with odder shapes like a rocketship, a gun, and even enlarged versions of some of the pentominoes themselves. Each level is timed, and once the timer is started it cannot be stopped until the level is finished. One starts off the game with only three pentomino pieces, and at the completion of each early level, a new piece is awarded to the player. At the final level, the player is given the 2x2 square O tetromino
and must complete an 8x8 square puzzle.
After completing each level, the player was given a password to access that level at a later time. Interestingly, each password was a common English four-letter word, so that by guessing common four-letter words, players could potentially access levels they had not actually reached by playing the game.
The name of the game was inspired by Daedalus, the mythical character of Greek legend who created the labyrinth.
A faithful fan version was later coded for the MSX computer system by Karoshi Corporation in 2006 for the game development contest MSXdev'06
The game has been ported to different platforms, such as PC and GP2X.
