Bedroom Battle is a game for couples where you play against each other to win rewards in the form of sexy favors. The concept is very simple. Each game round you use battle cards to compete for a reward card containing three different sexy challenges. The winner of the round then gets to select one of the sexy challenges for you both to act out. Once you have completed the challenge you move on to the next round and start playing for a new reward card. To make things interesting the rewards will become more and more naughty until the game ends with the final reward - which of course is the naughtiest of them all. Naughty Winter Nights contains 21 Christmas-themed battle cards and 54 challenges that are either romantic or extra kinky. —description from the publisher
