@Joshuamcvey If you don’t pay for a subscription, you’ll see where your results for each game you play fall as far as a percentile of the total player base. And you’ll only have one free game per game type to play every day. If you pay for the subscription you get access to archives and the leaderboard.
@Joshuamcvey The links they provide expire after a short amount of time, but if I am able to get another one, I’ll pass it along. In the meantime, you can play the other games on the site via individual game apps available in your relevant app store: SpellTower, TypeShift, Knotwords, and Really Bad Chess. Besides a daily crossword puzzle and the Flipart game (which I’m not sure if they have released as a separate mobile game), that’s what’s on the site.
