[*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 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!

The best

I am under the age of 20 meaning I wasn’t even alive during the age of interactive fiction when Infocom was actually a company. Yet most video games today don’t offer the player the random and sporadic thinking required to win, making those games boring and repetitive. I love reading as well and can’t get enough of a good story. When I discovered interactive fiction it satisfied both of those desires. So many of these games are extremely challenging and hold a unique story that always has something unique. These games take a lot of time and effort however this is the best app in the App Store I’ve ever had.

Fun to play, functional, some improvements can be made.

I have enjoyed Frotz for the most part. My only complaint is that many games are intended to be played with specific features that are not included here. For instance: The Dreamhold is intended to have a built in map that develops as you explore, which is not included. This made the game more difficult, however, I was able to finish (with some help from the interweb). Another example: Photopia is intended to be played with multicolor text which is not included here. I have not played much Photopia yet, so I'm not sure how this will affect gameplay. My experience has been that these problems make the games convenient, but never impossible. As for praise: I have had nothing but fun playing the games here, and the app moves smoothly. The catalog of games is very impressive and I can't wait to play them all!

A huge thank you

To the dev of this app. I love it, have used it for many years in ios and will continue to for as long as you support it.

2 suggestions:

1. Interface options.
If you ever get the itch, providing more choices in readability would be appreciated. The use of color to highlight key words, the old ios infocom treasures app did some pretty nice formatting things that you could look at, for improving this app.
Or not. I love this app as is, and would rather you keep it going as is, then develop it further, get burned out and stop supporting it at some point in the future. So it’s just a thought.

2. Add a “pro” version. Charge a few bucks for it, as an in app purchase, or whatever. Even if it offers no additional features. I will gladly toss some dollars your way, just as thanks for what you have already done.
