Did you click the info icon in the bottom-left? That should show the required terms.

Yeah my algorithm for determining spam and/or bad attempts isn't very advanced. I intend the site to help teach brevity to people who already know English well, so while it might be nice for the game to detect mangled text, it's not really a priority. I suppose people who want the functionality could use one of the automated writing assistant browser extensions for now.

One could "cheat" by submitting mangled text for amazing scores, but that would defeat the purpose of the game and be a waste of time :)
