Set Swarm

Set Swarm is SET solitaire with one shared daily deck: 81 unique cards built from four traits (shape, colour, count, fill), twelve laid face-up at a time. Tap three cards — when every trait is all the same or all different, the set clears and three fresh cards slide in from the stack. An invalid trio just shakes and is logged, never punished. If the board runs out of sets, three more cards are dealt; when the deck can't help, the run ends and your set count lands in an honest world histogram. One hint per run reveals a set (clearly flagged in the result), practice decks are seeded from your device, and the daily deck is identical for every player.
