This is my go-to time waster. Easy to play, can pause if something comes up and return later, and amusing too. One issue is that some real (and fairly common) words dont count while some very archaic ones do. So try some weird combinations and you may hit it lucky. Always try for the six letter word first - get at least one and you are guaranteed to advance to the next level even if you miss lots of smaller words.
