A little more about the activity
Enter a night market where every collector wants something different. Moonlight Market: The Secret Collector Auction is a printable auction card game for adults, combining hidden collection goals, limited Moon Coins and secret bids. Build a collection that fits your goal while trying not to reveal too much about what you want.
As unusual items come up for auction, everyone decides what to bid. Matching bids cancel each other out, and the highest remaining positive bid wins. That means a lower bid can win if other players choose the same higher amount. If no positive bid is unique, the item goes unsold. Different items and secret goals change the decisions from one game to the next, with bluffing and unexpected wins packed into a typical 15–30-minute session.
Play with 2–5 players in total for a date night or small-group game evening. No host is needed. You can play with human players only or add optional AI opponents, who count toward the player total. At least one player must be human, and one adult human can play against one AI. The AI joins as a competing collector, rather than running the game. Access to an AI service is not included.
For adults who enjoy secret bids, curious collections and a little friendly competition.
