Red Dragon Inn: Allies - Spyke & Flower - Rules of Play says:
The Red Dragon Inn: Allies – Spyke and Flower is our first standalone Allies expansion, letting two players drink, brawl and gamble the night away to prove that they are the best munchkin around. It contains everything you need to play the game, including a brand new Drink Deck as well as a new automated third-player game variant. So play head to head with a friend, or combine this game with any of our other The Red Dragon Inn sets for parties of three or more players.
