Z-Comp (also called "Z-machine Compo") is a competition for writing Z-machine games. They are held on ifMUD; enter apartment 11011 (one way to do so is "@tel #20080" and then go into the apartment) and go northwest.

Alternatively, you may send a message to the organizer and he will put it in for you, if you prefer this way. However, if you do send a message instead of using the form, you should submit a few days early (the organizer then has to submit the form for you by the deadline instead). (Many people think the other way is too convoluted; it isn't, but now this other way is available if you prefer.)

Z-Comp is written partially in JotaCode and partially in SQL.

There are plans that other VMs may be added later on (with some rules specific to each VM), rather than only Z-machine. However, this is not yet done. Some of them might be:

  • Z-machine 1,2,3,4,5,7,8 (using Infocom's specifications, with extended versions 7 and 8)
  • Level 9 A-code
  • iNES ROM images (use of Family BASIC Keyboard)
  • TAIL (Text Adventure Intermediate Language)
  • VM360/TA

Important Note: Failure to follow the theme isn't grounds for disqualification, although your score may go down if you don't follow it. If you get good scores in the other categories, then it shouldn't matter so much, though. Feel free to completely ignore the theme if you want!


This is a copy of the rules. In case of disagreement (hopefully there isn't any!), the ones on the ifMUD are canonical, though.

(Deleted due to being outdated; please see ifMUD; this may be updated in the future)
