is played over three rounds, with each round consisting of four turns. On each turn, players simultaneously and secretly choose three colored cylinders from behind their screen. Then, in turn order, they place matching colored assistants on their player board and perform the corresponding action, then all cylinders are placed in the cube tower. Then, 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.
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.
