After playing Carcassonne once I was instantly hooked. Briefly, the game consists of the following. Players pull a tile from the deck and place it against an already present tile. If you create a new object (a city, a road, a monastery, or a farm), you can claim ownership to it. Your score depends on the items you own, whether or not they have been completed and how developed they are.
To win the game you need good strategy and luck. The rules are easy to learn, and the game can be finished within the hour so you can play it more than once in one evening.
To play the game you will need Carcassonne, the original game. There are many expansions available that can only be played with the original game. There are also variants to the original game that cannot be played with the expansions. So read the description carefully before you purchase any additional items.
When purchasing the original Carcassonne I strongly recommend that you also buy at the least the first Expansion: Inns and Cathedrals, which makes the game more challenging and with higher risks.
