Puzzle #7: "Four-Letter Words"
Odd grid size today (7×13) with a concept you've probably seen before (if you haven't and/or you're stumped, check out the solution). I like how the stacks of 7 each "turn the corner" into one another — it reminds me of certain space-filling curves in mathematics.
I missed mentioning it earlier, but my sincere thanks to puzzle guru Will Nediger for the shoutout on his blog, Bewilderingly! Will's been a gracious and encouraging mentor, patiently test-solving and critiquing many of my puzzles.
