Emma and I are now selling themed puzzle sets for use as entertaining party favours for events like weddings, and stag and hen parties. The idea is that you'd buy enough to give one to every attendee, and people who want to can try to solve it, and regardless they can take it home afterwards. There's also a competitive element: each puzzle has a QR code inside which the successful player can scan to add their name, and solve time, to the event's private online leaderboard.
