The Hitchhiker's Guide to the Galaxy — it is pitch black Runs here
1984 · Infocom · System 6 · Mini vMac (Mac Plus) · 512×342 black and white
Guide updated September 2026
You wake up with a headache, the room spinning, and no light. The first thing the game wants from you is to turn on the light, and the second is to find your way out of a house that is about to be demolished. It goes downhill from there in the way the radio series did.
Douglas Adams co-wrote it with Steve Meretzky, and he was not a novelist lending his name — the famous cruelties are his. The Babel fish puzzle is a chain of six actions where every reasonable answer is wrong once. The game lies to you about your inventory. At one point it asks for something you could only have picked up an hour earlier, in a scene that gave you no reason to.
Boots straight into the game from the 1984 floppy. Type at the > prompt; the Commands menu lists the verbs it knows.
Controls
| Type + Return | Everything. This is a parser game. |
| LOOK / INVENTORY | Describe the room; list what you carry |
| Commands menu | The verbs the parser accepts, if you get stuck |
| SAVE / RESTORE | Save inside the emulated Mac. Do it often. |
Activision owns Infocom's catalogue and still exists. Hitchhiker's has not been sold since Classic Text Adventure Masterpieces went out of print in the late 1990s and is in no current product. The Zork trilogy is deliberately not on this site, because it is sold today.

|---|---|
| System | The floppy's own — this disk carries the System it shipped with |

| Release | 47 / serial 840914 |
| Saves | SAVE writes inside the emulated Mac, in your browser |
There are no graphics and there is no sound. What you get is a window of text and a prompt, which is the whole medium. The Macintosh version's contribution is the menus: the Commands menu is a list of verbs the parser understands, which is a real help in a game that is otherwise happy to let you flail.
The physical extras — the Don't Panic badge, the pocket fluff, the order for a microscopic space fleet — are not on the disk and never were.
Why it is remembered
It is genuinely hostile, and that is the joke. Most interactive fiction wants to be fair. Hitchhiker's treats unfairness as comic material: it withholds, it misdirects, and it kills you for things it never hinted at. Whether that is brilliant or insufferable is the argument people have been having about it since 1984.
The Babel fish. Five or six steps, each of which only reveals itself as necessary after the previous one fails. It became the standard example of the adventure-game puzzle you cannot reason your way through on the first pass, and Infocom sold a hint book largely on its strength.
It outsold almost everything Infocom made. Somewhere north of 350,000 copies, at a time when that was an enormous number, and it is the reason a licensed tie-in could be taken seriously as a work in its own right.
Getting started
Turn on the light. Get up. Get dressed. Take the things in the room before you leave, including the ones the game does not draw your attention to.
When you reach the pub, drink the beer — this is not optional and the game will not tell you why until much later. Keep a save before anything that looks like a set piece, because the game is perfectly willing to make a scene unwinnable without saying so.
If you have never played interactive fiction: the parser wants short imperative sentences. TAKE TOWEL. GO NORTH. EXAMINE SIGN. Type LOOK when you lose track of where you are, and read every room description twice — in this game the nouns matter.
Questions people ask
Is this the real Infocom game?
Yes — release 47 of the 1984 Macintosh version, the same story file Infocom shipped, running its own interpreter on an emulated Mac Plus.
Do I need to have read the books?
No. It follows the opening of the first book loosely and then goes its own way. Knowing the books helps with a couple of jokes and will not help with the puzzles.
What happened to the Babel fish puzzle?
It is here, intact, in all its unfairness. Expect to fail it several times; that is the designed experience.
Can I save my game?
Yes. Type SAVE. The save lives inside the emulated Macintosh in your browser, so use the same browser to come back to it.
Is there a graphics version?
No. The 2004 BBC browser edition added illustrations to a reimplementation; this is the original text game as Infocom released it.
Why is Zork not on this site?
Because it is still sold, as the Zork Anthology. Anything currently purchasable stays off macemu, however well known it is.
