Two things, one on-topic and the other off-topic:
The thing which makes 2048 moderately easy to reason about is that incoming pieces are always "1". However, this game appears to spawn in random pieces, with random point values. I tried to follow the to-and-fro of the design blog in order to find out why this is, and I get the impression it's for avoiding getting the player stuck, but it does have the disadvantage of making planning incredibly hard. The good news is that by reading the blog I finally understood what was going on with the screen shake
off-topic: that "Subscribe to me blog" modal is not only bad UX (imho, of course), but also doubles down on the UX tire-fire by resetting my reading position to the top of the page. It's almost enough to warrant a command-w right there. Just one datum, but it for sure made me sad
