The goal CASTRUM is to be the first player building his entire castle. The game is played from 2 to 4 players with cards. Getting cards on a pad, you collect the resources to build your castle and escape the dangers of medieval times. When you get resources you put the resource card in front of you on your construction site area. When you'll have enough resources to set up a wall or a tower, you can exchange the cards with wall pawn or tower pawn. Then you castle is built. It's a family game.
