About Dolphin

Listen! An endangered dolphin is calling you! Only by learning the dolphin's sonic language can you guide her through schools of seahorses, battling a monstrous squid, to gain magic powers from and elusive seagull. Hurry! Lend an ear... You will guide your dolphin through openings in the seahorse schools by listening to sonic tones and catching waves. Pay attention to the following: THE SEAGULL: Periodically, a seagull will fly overhead. You'll know he's coming when the squid changes color. Have your dolphin leap up, touch the seagull and then quickly turn and chase the squid. This is the best way to gain points. Also, the game resets at the next difficulty level putting distance between your dolphin and the squid. THE SLIP: Another great way to outsmart the squid is by giving him "the slip". If the squid is right on your tail, wait until he catches a good wave. Then, reverse your dolphin's direction and swim under him immediately. As long as the squid's good wave remains on the screen, he won't be able to reverse and catch you. SCORING: Points are earned in a variety of ways. Every time your dolphin touches a seagull, or a squid, you score points. The number of points depends on the color of the squid. Scoring peaks at 800 per seagull and 8000 per squid. Also, you'll score 100 points each time your dolphin catches a good wave or each time you run the squid into a bad wave. And, when your dolphin swims through the seahorses, you'll score 0 to 50 points, depending on your degree of accuracy in getting her through the opening.

Atari 2600 prices, all games & how to spot a fake

A side-scroller you play partly by ear, and an inexpensive Activision oddity.

Matthew Hubbard created Dolphin for the 2600, and Activision released it in May 1983. It is a side-scrolling game in which you have to listen to audio cues to survive, which sets it apart from most games on the system. Little else is documented about it.

What the press said at the time

Computer Entertainer Vol. 2 No. 2	May 1983	Graphics ★★★½ · Play-Action ★★★½
Electronic Fun with Computers & Games Vol. 1 No. 7	May 1983	3½ joysticks
Video Games Player Vol. 2 No. 1	August-September 1983	B

“The game itself is fascinating, although fans of heavy video action may find it a bit too cerebral.”
— Computer Entertainer, May 1983

“Dolphin is a solid game. It's challenging, but not too hard; visually striking, but not at the cost of game play; and above all, it's a game that you can almost beat.”
— Electronic Fun with Computers & Games, May 1983

“The innovative use of sound is a clever twist not found in many games.”
— Video Games Player, August-September 1983

“Whereas audio/visual effects merely enhance most games, players of Dolphin must use their ears as well as hands and eyes.”
— Electronic Games, September 1983

Computer Entertainer rated graphics first and play action second, from four symbols (excellent) to one (poor) — stars in most years, diamonds in 1986–87 — comparing each game only with other games for the same system. Electronic Fun rated games out of four joysticks. Video Games Player graded games like a report card, A+ down to C-.

Before you buy

Low risk; no reproductions are documented and loose copies are inexpensive. Because the game relies on sound, test it with the volume up before you buy a copy you intend to play.
