In turn order, players select a color and take 1-2 of the cylinders that have passed through the tower (or those that were stuck from a previous round but have now emerged) and place them on their player boards. These cylinders will enhance future actions taken in the same color in future rounds. Then, in turn order players will activate the regions where they have placed an assistant.
Actions allow players to gain wealth, which can be traded for influence in the city. Performing various actions also earns bonuses and enhances actions even more as the game proceeds. The player who scores the most points by the end of the game wins.
