Played this on the weekend and really enjoyed it. One rules question: when opportunity cards remain on the main board at the end of a round (because one or more players used the coin option to take a card from the deck), what happens to those cards.
The rules say that 4 new cards are placed at the start of the round but doesn't say what to do with the remaining cards. Are the old cards put at the bottom of the draw deck, or reshuffled in?
We went for placing them at the bottom of the deck.
