What's New in Cairn

3.4.0

October 3, 2026

Beyond Zork is here. Play it as it first appeared, with the room box, the on-screen map, stat bars and the combat monitor drawn in the game's own character graphics, or switch to Normal mode for a classic status line and transcript. Switch any time from the play bar on iPhone and iPad or the Game menu on every device, and your choice is kept in your saved game. - On iPhone and iPad, on-screen arrow keys drive character setup and the SETTINGS screen, and scroll the room box when a description runs long. - The screen scales to fit an iPhone held upright and leaves room for the story's replies when it is held sideways. - Cairn's map follows you through the forest, moor and plain, naming each place as the game does, and keeps each room's full description even when it is too long for the game's box. Group your library by date, from Today and Yesterday back through earlier years, with the headings following your sort. In grid view, any grouping can sit on sideways shelves or wrap into rows, on iPhone, iPad and Mac. Fixes - On the Mac, the arrow keys now move through menus that wait for a single keystroke, such as Anchorhead's help. - On the Mac, grouped covers in grid view wrap into rows unless you choose shelves. Covers grow with the window and fill the list, and as you drag the library's divider they glide into new rows instead of jumping. Maximizing the window no longer stretches the list past its widest. - Commands with a dollar sign now work. $VERIFY checks the story file in Zork and the rest of the Infocom catalog instead of answering "I don't know the word", and in Zork: The Undiscovered Underground you can pick up the ZM$100000 candy bar. - With unexplored exits shown, the map no longer marks a way out through a secret door you haven't found yet, such as the dead end in Curses' attic.

Accept no substitute.

The absolute best at what it does.

Wonderful interpreter

Loads of polish and fun in this application. And with one purchase it’s on all supported devices. Hands down one of the best interpreters, library, and notes feature I’ve seen for interactive fiction.

Amazing

This app is great. The auto mapping feature is super helpful!

Response from developer

Glad you are enjoying Cairn! Keep an eye out for updates. We've got some mapping improvements planned in the coming months. Thanks for your support!

Well worth the price!

You would once upon a time pay $20 for a collection of Infocom games on CD-ROM. Today that gets you an app on which you can play not only the majority of Infocom’s catalog, but untold numbers of other interactive fiction games. The integration of mapping and hints is seamless, and the UX is excellent. Controls are intuitive and everything is highly customizable. A must-have app for any fan of text adventures, classic and/or contemporary.

Response from developer

Thanks for the review! IFDB is a great place to look for 3rd party stories. There is a robust community who are keeping interactive fiction alive.

Simply Fantastic

I’ve been looking for a replacement to The Lost Treasures of Infocom ever since Activision abandoned it and never made a 64-bit version. Enter Daniel Ducat. He made an app as good and even better than the original! You just need to do a little work to find the games and invisiclues, but that just adds to the fun. Now I can recycle my old 32-bit iPad.
