Around the time of the release of the NES and Game Boy versions of the game, Bullet-Proof Software advertised a contest in various video game magazines. The contest involved arranging pieces of a puzzle on a grid. The puzzles pieces themselves were drawings of pipes similar to what can be found in the actual game. The puzzle had a scoring guide and there were three prize levels for the entrants with the highest scores. 75 3rd prizes were BPS T-shirts, 25 2nd prizes were a free BPS game of the winner's choice and the above mentioned T-shirt, and 3 grand prize winners who would receive a free trip to Nintendo of America's headquarters in Seattle for 4 days and 3 nights. There was also a $1000 bonus drawing for contestants that answered two bonus questions. The questions revolved around knowing the scores on the back of the game boxes of both the NES and Game Boy versions of the game.

Macintosh version

The Mac version actually included two game programs. One was a full-on application while the other was a Desk Accessory which could be installed and run from the Apple menu over whatever regular application you were running. Pretty handy for slacking off on projects if you were working with an older version of the OS that didn't support Multi-tasking.


This is one of the most-ported games of its day, with versions for more than a dozen system in existence. Notably it was one of the few titles from a major company for the SAM Coupé, an intended successor to the ZX Spectrum (from a different company) which never succeeded due to compatibility issues and not being as powerful as the rival ST and Amiga, which both already had a vast library of available games.
