The only way I can imagine these trophies being obtained is by working through a personal list, that list being updated every time a new word is added.
I'm with Pat on this. I've been playing Chi for about 10 years now; I play every game nearly every day and most games I manage to get to within one or two words of a rosette; I can reach 'maven' on average about three or four times a month, I even got to 'cham' a couple of times last year, but I've never managed to get within sniffing distance of a trophy / cup. Not once!
Out of curiosity, I looked at the complete list of words in yesterday's
cellophane 10-letter game; Of a total of 138 words in that game, I managed to find 75. I missed one common word -
epochal - and about four or five rare words that I knew. Most of the other 60 or so uncommon words were totally unknown to me - some of them didn't even look like English words.
caneh?,
opah?. How can anyone know words such as these and recall them, and dozens of others like them, not once, but three times a day? Every day.
I've heard it argued that top Scrabble players memorise lists of words; that is true, but, as far as I know, top Scrabble players spend hours memorising long lists of
two- and three-letter words, since these are most useful to them in the closing stages of games. The chances of being able to play
panoche,
pechan and
phoca (God knows what any of them mean!) are remote indeed, so why would they bother memorising them?
Also, for the very top Scrabble players, there is money to be made - from tournaments, competitions and demonstration games, so they will spend hours and hours memorising word-lists.
As far as I know, there are no such openings for Chi players - not yet, anyway!
ps. Of the five obscure words I have mentioned in this post, only one -
opah, a large deep-water fish - is in COD.
