Not quite. I thought I had a lot of great words, but apparently I missed some even greater words. I could have spent another hour or so brainstorming and gotten a few better words, but I would still have missed the longest available words.
On the Blossom page, there is a "search dictionary" field at the top of the page. You can use that to test word spellings or even fish for words by typing a few letters and watching the autocomplete suggestions.
