The graphics and sound are pretty basic, but the strategy is interesting. There is a chat and multiplayer is possible or you can play against the computer at beginner or advanced level.
Each round starts off by increasing your resources. There are three types: bricks, weapons and crystals. For every builder, soldier or magic you have, you get one of each resource.

If you can't play a card, or if you choose not to, you will need to discard instead (hold the ctrl button and click on the card you wish to discard).
If you build your castle up to 100 or reduce your opponents castle to 0, you win the game.
