A logic puzzle every day, and a ruined estate that rises as you solve it. You are the Thirteenth Warden of a house that stands in nine worlds at once; Rune Weaving is how you put it back together.
One puzzle a day, the same one for every player. Every puzzle is proven solvable by reasoning alone, with one answer and no guessing. Spend what you earn on eight chambers and watch them change, read the Estate's story as you go, and take a break with five quick diversions.
For Android, iPhone and iPad, and the web.
