      Your friend plays the same market number and gets the same starting board. Scores stay on each device; nothing is sent anywhere.

      Who came shopping

        Every shop in this game is invented. None stands for a real business.

        How it works

        Each market has four customers. Each customer needs exactly four of the sixteen shops on the board.

        1. Pick four tiles you think serve the same customer, then press Open stall.
        2. If you are right, they lock into a market stall and you see who was shopping.
        3. If you are wrong, a lantern goes out. Four wrong offers are forgiven. A fifth closes the market.

        Many tiles look as if they could serve two customers. Before you offer, check that the other groups still work without the tile you are taking.

        Free tools

        Chalk marks let you sketch groups on the tiles. They never count as an offer. Line up marks moves them side by side so you can compare them.

        Scoring

        The last stall pays least, so finding the trickiest customers early scores most.
