My Boggle rules say 8+ letters is eleven points. That would mean there is no such thing as a twelve point word!
Unless I have an ancient version of Boggle. But then, Wikipedia and fun-with-words.com agree with my rules on the scoring. So, no twelve point word and I want my GG!
But in case it's an eight letter word we're looking for...
STEALING ENTRAILS PLEASERS
Also,
trails grails renters lasting tasting pasters
...plus a lot of little stuff.
Entrails is not a great word for the top of a cake. I was expecting something sentimental.
#2 in Boggle you're allowed to go all serpentine with your words; successive letters can be adjacent orthogonally or diagonally in any direction without regard to the directional relationship between the previous two letters, as long as you use each letter only once. In theory, sixteen letter words are possible.
According to my friend who made the cake, "Replasterings" isn't valid because it isn't in SOWPODS. I'm unaware of any debates about what dictionaries are valid or common with Boggle players, but my friend is scary into both Scrabble and Boggle, so I'm not disputing it.
