What is the best scrabble word ever?

quartz is the best Word you can make on Scrabble even if it is not on triple Word!!!

equinox is better because you will use all your letters and get a 50 point bonus!

Nah..."CONQUEST" down off top left or right triple Word score or across from top or bottom left triple Word score puts "Z" on double letter score - Word alone is worth 29 times by 3 times by 3 (lands on both triple Word scores) plus 50 for seven letter Word = 224. As it's an eight letter Word it needs another player to have already played a Word with one of the low value tiles in the right place.
