You can play single player or multi player. Single player can involve testing yourself question by question, or simply taking your time to match every pair on each page as it comes (like casually sifting through the question deck at Trivial Pursuit). Call me a nerd, but with a beer in hand that’s a quality night in!
Multi player options include playing on the same device (e.g. sitting round a table at say Christmas, just like a board game) or online with your amigos in the ether.
