There were a few boxes in the game I just played that didn't have enough information; e.g. only one number pointed to them and you couldn't reason it out. I think it's the kind of thing in regular minesweeper where it would've auto-cleared it when I opened a box next to it. I didn't take a screenshot but I hope that makes sense - I suppose maybe once you play the game more you'd learn that these are safe x's, but I found it to lack real information. I looked around for a tip or something on it but didn't quickly find anything
