Love to see the two constants LETTER_VALUE and LETTER_POOL up top! 🧡

This doesn't quite mimic the action of pulling out a random letter form a bag of properly weighted letters (here, there's an equal chance of pulling out a E as a Z due to L28, despite E being much more likely to be drawn) but it's a good start!

Great tiebreaker logic in a neat helper function!
