Hi everyone, I'm Paul. Drystone is a Suguru puzzle game for iPhone. The rules fit in a sentence: each block holds 1 up to its size, and no two identical numbers can touch, even diagonally. Most Suguru apps get harder by hiding more numbers, which is why their "expert" often plays like a warm-up. Drystone builds every board on your phone, solves it the way a person would, and grades it by the hardest technique that solve actually needed. So the puzzles never run out, and the difficulty means something. It also makes no network requests at all: no account, no ads, no analytics. The daily puzzle is worked out from the date, so everyone gets the same one without a server. Easy, Medium and the daily are free. £2.99 once unlocks Hard, Expert, unlimited puzzles and hints. I'd like to hear how the difficulty feels, especially at the Hard end.
