To build you still require resources. These are collected by a Yahtzee-like mechanism that involves throwing six special dice (depicting the different resource symbols) up to three times. After each roll, the player can select which dice to keep and which to roll again. In the end, he may build using the thusly determined resources, and is awarded victory points for any finished buildings, which are recorded on the scorecard.
The game lasts fifteen turns or about 15-30 minutes, after which the player with the most victory points wins.
Note that the game has been designed for 1-4 players, meaning there is a solitaire version of the game, as well.
