Show what is wrong when letters don't make a word, as in "Words With Friends". For example, ("te, tu ") instead of just a blank response.
Show what is wrong with a play.
A smart player will simply memorize every possible two letter word, for example. It’s not hard to do. Makes it easier to play words quickly.
In addition, I think it should show the word you are trying to spell. it could be above the bot, in the same place as the word and score appears. it is sometimes hard to picture the word if you are writing downwards.
there are too many "near words". Play could get very complicated.
It’s there in the way the letters are coloured, and in the tones you hear when you place them.
