Tumblestone is out now and free until August 15, 2016 on X-Box One Games with Gold program. Here’s a video uploaded to the Video Game Source Youtube channel showing the first 13 minutes of gameplay:
As you can see from the video, Tumblestone is a match 3 puzzle game. The game actually ramps up in difficulty pretty quickly. Maybe I just need to play the game more to understand the best strategy in clearing puzzles. It’s definitely worth a download to try out since the game is free until August 15, 2016 and about 1 gig in size.
