Once per week, each and every single person reading this blog post is allowed to e-mail a set of words to glmathgrant[at]gmail[dot]com. If it is a set of at least 10 words, I will publicly post on this blog (on the following Monday at 12:01 AM Central time) whether NONE, ONE, TWO, or ALL of my words are in that set. If it is a set of 9 words or fewer, I will privately give you the same information. If I can't easily verify whether a set of words has at least 10 words in it, I will assume it does, so if you want your information kept private, submit your set of words in the form "{CINQ, QADI, QAID, QATS, QOPH}" rather than "the set of all Scrabble-legal 4-letter words with a Q and not a U".
Once someone has guessed the trio of words (that is, submitted to me a set of exactly three words and gotten a result of ALL), one last weekly update will be posted on this blog, and then people who haven't guessed the words yet will have one more week to try to do so and be entered in the prize drawing.
This contest will also benefit the Food Bank of West Central Texas. The money pool which I will donate to them will start at $50, and then go down $2 for every weekly update that has gone by without someone guessing the trio of words. If the money pool would hit $0, I will instead withdraw the prize drawing. So even if you aren't interested in the prize drawing, your participation may help someone else solve the words faster and thus help charity!
To kick things off, I'll make four guesses for you, chosen from among the guesses that were made in Let's Guess Two Words II!:
The set of all words beginning with a letter between Q and Z inclusive: NONE
The set of all words whose letters have a combined point value of 15 or higher in English-language Scrabble (examples: JOKE, ZZZ): ONE
The set of all words where exactly two of the letters are A, E, I, O, U, or Y: TWO
The set of all words containing a double letter (examples: EGG, BOOT, LLAMA; counterexamples: FIFE, NANA): ALL
Good luck, and yappy guessing!
