Lexifind Help:
Super Scrabble
Super Scrabble is like Scrabble ®, only "bigger" in several ways. The main differences are as follows:
In every other important respect, Super Scrabble is the same as Scrabble ®. In particular, there are still at most seven letters available on the rack to be played prior to each turn.
Since Lexifind does not compute scoring, the presence of additional, different bonus squares has no effect upon your ability to use Lexifind when playing Super Scrabble. Likewise, the increased number of letters only makes the game last longer; there is no impact on how you would search for words.
This means that the only difference that matters for word search purposes is the increased maximum word size. The Scrabble-oriented lists used by Lexifind have no words larger than 15 letters. Therefore, there is no way to search for words that are longer than that, even though Super Scrabble allows words of up to 21 letters to be played.
Since there is still a maximum of seven letters that can be played during a single turn, the likelihood of creating a word longer than 15 letters is small.
Here at Lexifind we have not yet been able to identify any official word list for Super Scrabble. We are thinking about this problem, and it is possible that we will attempt to construct an unofficial Super Scrabble list by adding larger words to the existing Scrabble ® lists, but that project has not yet been scheduled or approved. In the meantime, we suggest that you settle on some outside dictionary that can be consulted on those rare occasions when someone is so rude as to play such an oversized word.
With the above caveats, we refer you to our regular Scrabble Help Pages for instructions on how to use Lexifind when you are playing Super Scrabble.
