If you're arriving here as a previous user of WordleUnlimited.com, welcome! You probably have some questions.
Unfortunately, the person that was running the site had to make the decision to shut it down. It was out of his control. And, rather than abandon all the users that were enjoying the game, he decided it would be better to send them here, to WordPlay.com.
It's a word-guessing game too, but with some additional features like saving your stats/streaks to a free account, using [space] to leave letter spots, etc. But, it's a *different* web application, so you're going to find some differences. Hopefully, on the whole, you enjoy WordPlay.
