It's nothing you haven't seen before.
Actually it might be something you haven't seen before. It was one of the reasons to purchase a Cybiko and was a fun little game, but it never seemed to catch on elsewhere. Ernie has a hexagonal version that's lots of fun, but there must be a daily puzzle version.
I'll see how far I get. I'll keep you posted.
Come to think of it, the Cybiko had a couple of great puzzles that would be perfect for the daily puzzle format. I'm starting to get bummed that I sold mine off.
