Blue Print is a maze game released in September 1983 as a port for the Atari 2600. The player controls J.J., who is on a mission to save his girlfriend Daisy from Ollie Ogre. To defeat Ollie, J.J. must find all the parts of a machine he has designed, assemble it, and use it to shoot Ollie. The game’s controls consist of a joystick and a button.
The screen is divided into three sections: the top section features a ledge on which Ollie chases Daisy; the center section is a maze of 10 houses; and the bottom section contains the machine’s blueprint, a “start button,” and a pit. Eight of the houses contain one machine part each, while the other two contain bombs. The contents of a house are revealed only when J.J. enters it. If a part is found, the player must move it to the proper position on the blueprint. If a bomb is found, the player must carry it to the pit before it explodes. Holding the button down allows for faster movement, but this speed boost is limited by an on-screen gauge.
Once the machine is fully assembled, J.J. must step on the start button and climb aboard the machine. The player then maneuvers left and right as the machine shoots balls upward. If Ollie is hit, he falls, and the level is complete. Bonus points are awarded for each remaining flowerpot on the ledge. A new level begins with the houses in a different configuration.
J.J. must avoid falling flowerpots, bouncing flowers, a creature named Fuzzy Wuzzy who roams the maze, and a monster named Sneaky Pete who occasionally disassembles the machine. J.J. must drag Pete back to the pit and set the fallen parts in place again to continue playing.
