An online telephone game you can play with friends, in your browser.
The default game rules see you all creating a two-word phrase, then each adding syllables to each others' phrases, until you end up with something very different to the phrase you started with. You can also create your own custom rules, and change the prompts players are responding to.
I'd recommend you play with 5+ players. If you're playing with <5 players you'll want to increase the number of rounds in the Custom Settings, or the game will probably end too soon.
