Thanks for the replies. I still do Wordle every day as a warm-up for Plusword - I find enough satisfaction in keeping my streak going on Wordle, but I'm beginning to wonder about Plusword.
Chris Lancaster at The Telegraph said on the anniversary webchat that he has about 4000 dictionary words to work with, plus any proper nouns. He can also weave in short two-word phrases. Some candidate words will be (near) impossible to fit into a grid, so with over 400 puzzles already devised each using 11 words, I wonder how many more he can wring out of this format?
I'm actually enjoying the NYT Connections puzzles these days (even if some of the connections are US-centric).
