As guessed correctly by 4 people, including 1 new participant, the trio of Scrabble-legal words was YOURS, MINE, and OURS. According to my calculations, this was one of 5 possible word trios based on the clues available after the final week (MINE could be replaced with COME, MODE, MOVE, or SOME).
The first winner of a $10 gift card for Grandmaster Puzzles plus a surprise gift, selected at random from among those 4 people, is Kevin Orfield! Congratulations!
In addition to Kevin Orfield, 5 other people meaningfully participated in the contest. The second winner of a $10 gift card for Grandmaster Puzzles plus a surprise gift, selected at random from among those 5 people, is Izak Bulten! Congratulations!
Wow, the same winners as last time. Random, I swear.
As a token of my gratitude to the few people who decided to endure this, I'm also giving the aforementioned surprise gift to all 4 of the remaining eligible participants (Cody McWilliams, John Bulten, Penni Bulten, yyw). Thank you all!
