From the publisher:
The knights set off from their castles to conquer the surrounding land. For the wealth of the big towns and the villages belonging to them is just too tempting.
Of course, once in possession, no knight wants to lose his newly acquired properties, so this means: caution. For the other players´knights are awake to any opportunity and the newly gained land may be lost again just as quickly to a new lord.
Bring your landscape tiles and above all your knights skilfully into play, secure your properties on all sides and watch out for enemy knights at all time.
Each player has an identical set of tiles, arranged with B's on top and E's on bottom. Of the 4 A tiles, choose a castle and another tile for your hand; the others (from all players) form a random starting play area.
On your turn, you place 1, 2 or 3 tiles, immediately drawing a replacement after each placement. These are played one at a time, and must be orthogonally adjacent to what's already on the board. They may not extend beyond the play area (7x7, 9x9, or 10x10 for 2er, 3er, or 4er). If a placed tile has a castle, you bring 0-5 knights (discs) into play onto that castle. Then, you may move those knights in a straight line, placing a number of knights on each tile entered (including the castle) based on terrain: plains=1, forest=2, mountains=3 (lakes impassable). Max total of 4 knights/tile at end of movement; if you can't enter a hex (e.g., forest with 3 knights present), you may not move beyond it. May not skip any tiles. If other player knights are present, place yours in a stack on top.
The game ends when everyone has played all their tiles. Earn VP based on tiles controlled (knight on top of stack controls tile): castle=1VP, village=2VP, town=3VP. Most VP wins! Tie-breaker = most unused knights.
