[*Warning* Playing Frotz involves reading, thinking, and typing. If you just want to blow stuff up, this is not the app for you!]

Burned out on all the new-fangled graphics and dazzling eye candy on your shiny new iPhone or iPad? Nostalgic for a simpler time? Then take advantage of those crisp high-resolution fonts to relive the glory days of the Great Underground Empire, or play any of hundreds of great works from the Interactive Fiction archive.

Frotz lets you play free works of Interactive Fiction (a.k.a. text adventure games) on your iPhone, iPod Touch, or iPad.

Frotz plays titles written in the Z-Machine format (which was invented by Infocom and was used to produce classic text adventures from the 80s such as the Zork Trilogy, Hitchhiker's Guide to the Galaxy, and Trinity), as well as glulx and TADS formats.

In the past couple of decades, text adventures have experienced a renaissance of sorts due to the efforts of a diverse Internet community of talented interactive fiction writers and fans. Many of these games are written using the same engine that powered Infocom's titles, thanks to the Inform compiler and authoring system created by Graham Nelson.

NOTE! If you have suggestions for improving Frotz or encounter bugs, please go to the support link and report them.

Best iPhone game ever! :)

I loved the old Infocom text adventures (Zork, Hitch-Hikers, Leather Goddesses, Planetfall) on my Commodore 64 way back when, and now I can relive them, the whole lot of them, and every Inform adventure that pops up on the if-archive too. (you need to set up ftp/http files to get the Infocom titles on there, but that's a minor speedbump to real Infocom fans.)

Looks like the Author is keep to keep improving it, so it will be great to stick around for the ride. But already all the great text-adventures are perfectly playable. (horizontal and vertical) No minute-long waits for the 1541 disk-drive at every command either. hehe. Thanks for an awesome game.

I've been waiting for this. Now just add zork 2, 3 and non MIT Zork 1.

Glitch on iPad 2

The game is good, but there is a glitch - if I go into the help, I can't resume the game, it just gets stuck in help mode. I can't even restart the game, every time I select the game it goes back to being stuck in help.
