A couple of weeks ago, NimbleBit announced that they were looking for testers for their new upcoming game called Letterpad. It’s a word game that gives you a grid of 9 letters and tasks you with coming up with words from those letters that relate to a certain topic. Well, the game is just about complete at this point, and today NimbleBit have additionally announced that Letterpad will be playable on the forthcoming Apple Watch. Here you can see a mockup of what Letterpad will look like on the Apple Watch.

A couple of points to keep in mind: this will actually be based on a WatchKit extension embedded inside the iPhone app. You won’t be able to run Letterpad natively on the Apple Watch initially. And, because there doesn’t seem to be a way for developers to monetize extensions in iOS apps, the Watch “game” will likely come for free in the main iPhone app. Still, I think the idea of iPhone games extending to the Watch is pretty cool (imagine having remote inventory for RPGs or glanceable information for simulator games on your wrist) and I’m excited to see how others will take advantage of WatchKit for gaming.
