A forum for game threads.
At the beginning of a round, Person A provides a word, including both a phonetic transcription in the IPA and some sort of orthographic representation. For example, I believe this was the beginning of the current round:
Person B then takes a turn, applying a few sound changes to the word and showing both the "before" and "after":
Person C then takes a turn, applying a few sound changes of their own, starting from where Person B left off:
The game continues like this until someone decides to start a new round by providing a new word. In my experience, it's customary to wait until the current round has already been going on for at least a few pages of the thread before trying to start a new one. Also, it usually makes sense to wait until the word has been reduced to just one syllable and not much more can be done with it before introducing a new word.
Players can change the orthographic representation of the word as well. This has never been a strict rule, but again, in my experience, it's customary to wait at least 5-10 turns after the orthographic representation has been changed before changing it again.
