    The Daily Baffle▲14

    Hey everyone, I built a new daily puzzles site with all original formats that I'm releasing today called The Daily Baffle. This is the successor project to my simple puzzle Triword from last year. There's a mix of different puzzles, done in the style of a classic newspaper games page. I think you'll especially like the Pathword, but all of my friends have different favorites. Come find yours!
