Like how everything in 2000 started with a lowercase e, and everything in 2007 started with a lowercase i, Squaredle belongs to the "word puzzles ending in -dle so people will think we're the one that went viral during the pandemic" family. Really it's just Boggle.
If you've never played Boggle before, the goal is to make words of four or more letters by connecting a string of tiles. Connections can be up, down, left, right, or diagonal, but once a tile is used, you can't reuse it for that word.
I've played each of the last three days, and you have to find between 40 and 70 words, so it keeps me occupied at work, and I can just go do my job or read chosts or whatever in between. It takes all day to finish one of these, which for the time being, I am enjoying more than I did the original Wordle.
