New fun from Matt Gaffney for all you meta-heads! Matt has a new weekly crossword feature at Merriam-Webster’s website. It’s a meta-ish feature that he created especially for their site, and it’s called “The Missing Letter.” There’s a new 15×15 puzzle posted each Monday at noon ET. The way it works is: 25 clues in each puzzle are definitions taken directly from Merriam-Webster’s Collegiate Dictionary (way more fun than it may sound like at first). They begin with 25 different letters of the alphabet; when you’re done solving, the one letter of the alphabet that doesn’t begin one of those words is that week’s “Missing Letter.” Submit that Missing Letter for a chance to win a $25 gift certificate to M-W’s site (the solving app keeps track onscreen of which letters you’ve already used, so there’s no cumbersome aspect to determining the missing letter when you’re done). Give it a shot here: https://www.merriam-webster.com/games/missing-letter. Deadline to enter is Sundays at noon ET. Good luck!
