    18 Words, Zanagrams and Sunflowers Are Now PZL Games▲8

    A few months ago I shared 18 Words, Zanagrams and Sunflowers here, which loads of you ended up playing and sending really useful feedback. I’ve now brought all three together into PZL games along with three new daily games. Just wanted to say thanks to everyone here who played, commented and helped improve them. HN has been a big part of getting these games off the ground. I'v now had over 1 million players across them. Would love to hear what you think of the new site, and any feedback is very welcome.
