There are multiple different ways to win a game of Kings and Assassins, and sometimes you're going to have to pick between them on the fly. Plans go wrong, so having a backup is going to be super important here. The king wins if he gets to his castle within the turn limit, but he'll also win if his knights capture or kill all three of the assassins. The assassins win if they manage to kill the king, but they'll also score a victory if the king isn't safely home by the end of the game. Always be ready to try the second option if your first course of action hasn't come off as you'd hoped. Lost two assassins trying to kill the king? Keep the third safe, and royalty away from the gates, and you can snatch victory from the jaws of defeat.
