This game is usually played in a setting (like a classroom) when each player has to think fast in a short time (30 seconds or so) without any help.
If we play this game on the forum when everyone has an unlimited time to think with unlimted help resources (dictionary, Internet...etc), this game will take forever to end. And it might get to the point that the word is used again.
I have a suggestion. With the same rules as DeMen stated, we could add an additional rule: Words can be found only in a setting such as only in school (or in a supermarket, or at a park, or in a bookstore, or at a party...etc). With such rule, the game will be more challenging and will have an end. Also, everyone can learn the vocabulary better since we focus on one topic.
