Each letter is given a weight and it's multiplied by the length of the word it's part of to get its effective weight. Sum it up for all letters and you get the final score. Here, it seems like two 10 letter words can be formed using the given 20. Hint - blackboard is one such word.
Thanks for playing! Right now the score is calculated by letter value multiplied by word length so longer words score more points. Open to feedback on this as wasn't sure best scoring.
I think a mix of word length and rarity might be the way to go. Information entropy would be a helpful approach here (look up the 3Brown1Blue video on Wordle).
I disagree on the rarity piece, I think it will be more frustrating if you can't predict how to improve your score. Length is straightforward because you know your strategy should always be to make the fewest longest words.
Using all letters giving a score of 227/380
There should be some hints on how to increase my score? Is this based on the word rarity?
