Each round an adventure card is revealed, showing the position of the castles and dragons as well as the knight’s starting position on each player’s board. Then, all players simultaneously attempt to find a path for their knights to reach all castles while regarding all the rules.
Whoever discovers the solution first, wins the round.
But watch out: While at first it may be optional to fight dragons, every round you win will force you to fight a dragon in all following rounds, making the game more difficult. The first player to win 3 rounds, is the winner.
