[*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. This format 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.

In the past decade, text adventures have experienced a renaissance 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. I have no way to respond if you only report bugs in reviews!

[Note from developer]

A comment to XnicknameX and anyone else worried about Dropbox security:
Dropbox authentication is done by launching the Dropbox app, which is the only app which sees your password. Frotz is then given a random authentication token or “cookie”, which it uses to access your account. Frotz will only access files within the /Frotz/Saves folder in your Dropbox. You can login to Dropbox directly and revoke authorization to any app you’ve previously given permission any time you want, which will then invalidate the cookie so it doesn’t work anymore.
iCloud drive support is planned for the future. (Doing so requires dropping support for older iOS versions, so I’ve put it off until I could get as many features and bug fixes as possible into the current version because it will be the last version users of very old devices which can’t run iOS 7/8 will be able to use.)

My top app--thanks for the update!

Frotz is just brilliant. I don't know what I would do without it. With it, I am able to have so many varied, exciting, challenging, and often deeply moving games on my iPhone with me at all times.

These games make you think. This app makes them shine. THANK YOU for the gorgeous update--my iPhone 6 Plus screen is the best experience yet for Frotz now, both portable and spacious.

Excellent and great support

I have long wanted to play classics like Zork and Planetfall wherever I am. I have seen different attempts on phones over the years and this is the best. It has a great library of free games and is quickly updated for new devices and screens.
